Numerical Simulation on the Propagation of an Internal Wave in Multifluid
We numerically investigate the propagation of surface and internal waves which are caused by a gravity current in a container. A level set approach is used to capture interfaces without explicit tracking. To model the complex boundary of the container, a virtual boundary method is applied to the level set formulation. In this study, it is shown that multifluid flows in a deformed container can be simulated through the combination of the above two methods.
