Abstract:

Interaction dynamics of rigid/deformable particles are included in a wide range of industrial and scientific approaches. The description of the binary collision of particles is required to predict the flow of a concentrated emulsion. The present review introduces the numerical approaches employed to simulate the interaction of two particles and evaluates the impact of deformability, configuration, and flow type on collision dynamics. Two closely interacting drops/bubbles can collide in in-line and side-by-side configurations in Newtonian and non-Newtonian surrounding fluids. Based on the previous investigations, the future trends for the binary collision of deformable particles are provided.

Keywords: Binary collision; Drop; Bubble; In-line; Side-by-side
