Abstract: The work reported in the present thesis is intended to study two kinds of droplet wall interaction flows: interactions between wall impinging drops and rebound control and transport. A high-density ratio based phase-field lattice Boltzmann multiphase solver is developed to investigate the present two phase computations. Two different interaction modes were identified for drops impinging successively and simultaneously on dry walls. It is observed that the droplet behavior in these modes was significantly influenced by the corresponding advancing and receding contact angles. The current thesis presents a new method to suppress drop rebound though wall oscillations along the transverse direction, normal to the line of impact. Droplet jumping process thorugh electrowetting is classifed into four regimes.
