Lattice Boltzmann Simulations of Drop Impingement on Walls

The lattice Boltzmann method (LBM) (Chen and Doolen, 1998; Succi 2001) [1, 2] is employed to simulate drop impingement. The Weber number range considered is 1 to 200 and Ohnesorge number range is 0.01 to 0.001. Different stages of evolution of the impinged drop, namely, spreading, recoil and oscillation are reproduced. A model is proposed and applied to simulate wettability. The prediction of the transient evolution of the impinged drop and wettability effects are the new contributions of this work. \newline \newline \textbf{References} \newline [1] Chen, S. and Doolen, G.D., \textit{Ann.
