Influence of geometry on mobilization of trapped blob

The capillarity induced resonance has been one of the promising method as far as the mobilization of trapped blob is concerned. The dependence of mobilization of blob on geometrical configuration is studied in conjunction with capillarity induced resonance. In this context, lattice Boltzmann Shan and Chen model is employed to investigate the mobilization of a three-dimensional immiscible blob subject to acoustic excitation trapped in the channels of different geometrical configurations. The influence of physicochemical parameters which include geometry, wettability and frequency on blob dynamics is discussed. The role of geometry on mobilization of the trapped blob is studied to understand the structure-wettability relationship.
