He has over 350 technical publications, including 7 books/book-chapters and more than 60 journal papers. He is Fellow of American Nuclear Society (ANS) and recipient of the 2014 ANS Compton Award.


Unlike single-phase flows, where the main factor behind the quality of computer simulations, with some notable exceptions, is mainly associated with numerical issues, two- or multiphase problems introduce a whole spectrum of additional questions, including but not limited to the: consistency of formulation of both individual models of interfacial phenomena and of the combined interconnected models, impact of differences between the modeling approaches used for multiphase fluid mechanics and for heat transfer, impact of fluid property models, needs to accommodate mechanisms of different scales (both spatial and temporal) into single computational models, numerical stability and convergence, criteria for assessing the correctness of computational grid selection (which may be quite different from those for single-phase flows), and criteria to quantify modeling vs. computational uncertainties. The objective of this lecture is to present an overview of the issues mentioned above, and to discuss recommended solutions based on lessons learned to date. Fluid-mechanics models of multiphase flow will be discussed first, followed by heat transfer with phase change (including both boiling and condensation). The impact of coupling between these two groups of models will also be addressed.

This presentation will be an overview of the educational and professional life of a university professor of Mechanical Engineering, researcher, and expert in his field. The presenter will demonstrate how a combination of events including life circumstances can dramatically change the direction of one’s career. The presenter will encourage attendees to not be fearful of those changes, but to embrace them as unknowns that have the potential to become exciting challenges that may enrich their careers. PowerPoint slides will illustrate the 40 year journey the presenter, has taken, from being a student of Mechanical Engineering in Poland to being an expert in traumatic brain injury (TBI) in the United States. The slides will also emphasize how the presenter followed a career path, but remained open to new opportunities, needs for research, communication, and technology that emerged along the way. Sometimes, professionals find themselves stuck in a career or reach the stage of burn-out. The goal of the presentation will be to motivate conference participants to continually look for new opportunities, where they can use their energy and talents, and to remember that their professional life does not have to be a linear path.

Rick James

Simu Tech Group, USA

Keynote: Digitalization & aerospace: The next era of engineering simulations

Time : 10:45-11:15

OMICS International Mech Aero 2017 International Conference Keynote Speaker Rick James photo

Rick James leads SimuTech Group’s team of 85 professionals who focus on simulation-driven product consulting, training and mentoring in structural, thermal, fluids, electrical, RF, electromechanical, signal integrity, drop test, and probabilistic design. He is an expert in FEA and CFD and has excelled as a consultant, expert witness, trainer, and leader. He has a BS and an MS in Mechanical Engineering and a DrEng in Engineering Management, all from Southern Methodist University in Dallas, Texas. He holds electrical and mechanical patents in semiconductor packaging and sits on the Board for Knowledge at Southern Methodist University’s Department of Mechanical Engineering.


One of the next eras of economic value from engineering simulation such as CFD and FEA will come from combining it with Industrial Internet of Things (IIoT) and digital twin (DT) methodologies. The simulation-based digital twin will help companies analyze smart machines in real-world operating conditions and make informed decisions that will improve their performance far above what is possible today. Physics-based and system simulations with big data analytics and industrial devices augmented with embedded intelligence can reduce risk, avoid unplanned downtime, and speed up new product development. The resulting efficiency and productivity gains will have a dramatic effect on an organization’s bottom line, as well as on the global economy. Engineering simulation has long been used to improve the design of nearly every type of physical product or process by evaluating multiple alternative designs before physical prototypes are built. Simulation has also been used for decades to model different operating scenarios to develop control strategies. These data and workflows can be incorporated into control algorithms to improve operations. The emerging IIoT has created the potential for a transformational voyage in which a product or process simulation model is tied, through the Internet, to sensors capturing data and to actuators controlling its operation. The digital twin of the physical product or process can be used to analyze, perform diagnostics and troubleshooting in real time, anticipate and communicate breakdowns, determine the optimal point to perform maintenance, tune the product to optimize its performance, and capture information that can be used to improve the next-generation design. The economic value is real and significant. There are fundamental core components that comprise a successful DT strategy, such as a full-fidelity simulation model that captures all multi-physics interactions; an IIoT platform such as GE’s Predix, Amazon’s AWS, or Microsoft’s Azure; a systems-level control over the simulation model (1-D logic layout), sensor data inputs into the IIoT platform; and a tool or method for creating a reduced-order model (ROM) of the simulation model. A CPU-intensive full-fidelity simulation model typically cannot be a component of digital twins because most simulation models require hours, days, or months of single-core CPU-equivalent solve time, thus the need for the ROM. The result is that a properly tuned digital twin can be used to substantially increase the performance and reliability of the product or process while reducing its operating cost. The digital twin methodology allows for less unplanned downtime, improved product development feedback, increased reliability, lower maintenance costs, and better predictive and prescriptive maintenance. This discussion will cover both conceptual and practical ideas about these core components in order to illuminate the overall economic opportunity, basic technical components, and workflows. Some of the likely obstacles to a successful implementation will be reviewed, such as how original equipment manufacturers (OEM) are not necessarily the same company using the equipment in downstream production. The importance of standards for data compatibility will be addressed. High-level protocols for the ROM will be suggested and combined with an overview of what a simple verification and validation (V&V) program could look like for an OEM to maximize the value and relevance of their simulation workflow and models.

Pulsatile flows, unsteady phenomena, coherent vortical structures, and transitional or turbulent flows at low Reynolds numbers occur in the human body. Examples of pathological blood flow in which unsteadiness, separation and turbulence are important include regurgitant heart valves, stenosis or blockages, stents, and arterial branches and bifurcations. Speech production involves unsteady pulsatile flow and turbulent structures that affect the aeroacoustics and fluid-tissue interaction. The overall goal of our cardiovascular-inspired research program is to understand secondary flow structures in arteries and to assess their potential impact on vascular health and disease progression. The richness of morphologies and physics of secondary flow vortical structures and their formation and subsequent loss of coherence during deceleration phases suggests implications related to the blood flow in diseased, stented and stent-fractured conditions. The goal of our human phonation research program is to investigate the dynamics of flow past the vocal folds (VF) and the aerodynamic interaction with the VF. Studies are performed under both normal and pathological conditions of speech. In particular, recent attention has been focused on understanding the aging voice. Our overarching motivation for studying flows relevant to biomedical applications is to facilitate evaluation and design of treatment interventions and for surgical planning, i.e. to enable physicians to assess the outcomes of surgical procedures by using faithful computer simulations.

The current National Science Foundation (NSF) - Engineering Research Center (ERC) is transforming the current medical and surgical treatments by creating "smart" implants for craniofacial, dental, orthopedic, cardiovascular, thoracic and neural interventions. The ERC is developing biodegradable metals with the premise that new kinds of implants can adapt to the human body and eventually dissolve when no longer needed, eliminating multiple surgeries and reduce health care costs. Magnesium based biodegradable systems offer significant therapeutic advantages over implants used today. Breakthrough activities include development, processing and testing of novel degradable alloy systems, new improved versions of existing clinical-use plates, screws and stents, innovative nanocoating technologies to yield special surface functionalities and methods to control implant corrosion, biocompatibility and improved bone growth. Additionally, the Mg based alloys are widely acknowledged to have enormous potential for lightweight structural applications, given their low density, high specific strength, good castability and better damping capacity. However, to actualize the widespread interest in Mg-alloys for light weighting applications, focused efforts are required to reach the strength, ductility, and corrosion resistance design end goals

The talk will specifically provide a scientific update on the various innovations, translation and trailblazing pathways for developing the biodegradable implants to light weighting applications through holistic University- Industry partnerships for economic ecosystem and commercialization

The surge of interest in space exploration to reach various planets in our galaxy would create opportunities for mankind to develop products and processes for low orbit and deep space long duration travels. In such cases, product malfunction in missions such as those to Mars may jeopardize the safety of the astronauts and termination of such missions. In this talk, a novel approach to develop in-situ manufacturing is developed in creating a workshop in orbit as a mobile repair and production center. The same workshop could be placed on the surface of a planet in preparation of establishing colonies of habitations. The approach taken in this study would require development of Modular Manufacturing Systems (MMS), where manufacturing process takes place in one and the astronaut as the supervisor will operate in the other in developing a solution for cost-effective placement of modular units in orbit for in-situ manufacturing. The self-contained modular units can be configured to meet payload transportation requirements, and to accommodate a wide range of space-based manufacturing needs. The MMS is designed to provide a safe in-situ environment for manufacturing and operational capabilities while meeting the challenges of outer space including radiation, temperature, and pressure contingencies. With current interest in long-term exploration of space including the creation of habitats on the Moon and Mars, MMS is designed to make all aspects of this endeavor possible cost effectively and safely. The MMS is constructed in the form of a cylindrical vessel that can be configured to contain one of many different sliding floor-mounted equipment assemblies. A functional manufacturing system consists of at least two such modules, one housing the astronauts with a sliding floor configured to provide the basic requirement of an astronaut such as life support system and environmental controls (temperature, pressure) as well as communications and control systems, and the adjoining modular to house a sliding floor containing the robotic machine fabrication equipment, raw materials and tooling. These two separate modules are connected such that the astronauts can safely supervise and control the manufacturing operation via visual through a viewing port as well as the cameras at various stages. This will allow astronauts to prepare set up, monitor and initiate automatic machining and fabrication of parts using tracked-robotic equipment. Since space-based manufacturing is a very new endeavor, astronaut safety must be a primary concern. The design of the MMS provides critical safety separation, override and supervision features. A modular manufacturing system could be configured to a variety of applications such as habitats for space travelers or a work/live environment for scientific/manufacturing space in providing a safe and sustainable habitat for deep space long duration missions.
