Acoustic waves is known to influence fluid motion. This project's focus in on the results of recent experiments showing that acoustic driving can be used to produce spreading of fluids on substrates. The component of the project at NJIT considers theoretical and computational aspects, and in particular focuses on formulating a model describing coupling of fluid motion and an applied acoustic field, as well as on developing appropriate computational methods for solving the nonlinear partial different equation governing the fluid motion. The participating students have worked on the project jointly with the lab assistant Joseph D'Addesa, for whom this project is a part of his PhD research. Figure illustrates an example of a numerical solution showing flow of a thin film over an obstacle. The numerical code used is deposited at GitHub. .
