Abstract
The Multi-Relaxation Time Lattice Boltzmann method has been employed to investigate the behavior the circled droplets and semi circled droplets placed on the side walls. A density distribution function has been introduced for each fluid and was utilized to simulate the dynamics of the side wall circled and semi circled droplets and the velocity field of each phase. Buoyancy and other interactive forces between phases are modeled to predict the evolution of droplets as they are rising. A fully periodic domain and no slip boundaries are employed in this study and the result is a transient flow simulation of a multi-phase immiscible fluid for geometries ranging from a single circled and semi circled droplet case to a case with two adjacent droplets. Also studied here is the interaction between the droplets and the no-slip boundary. The evolution of the droplets and the transient flow field around it are examined when droplets are placed on the no-slip surface initially. The breaking up of the droplet is predicted for different arrangements.
