Two-dimension numerical internal wave tank for Navier-Stokes equation model in the stratified fluid

摘要：

Based on the Navier-Stokes equation model and the interface-tracing technique of VOF, the numerical internal wave tank for a two-layer uid system is established by using the designed mass and momentum source functions. It has been shown that the monochromatic interfacial wave and the interfacial solitary wave can be generated in the numerical tank, as well as the scattering waves from the wall boundaries or structures can be eliminated effectively. The obtained numerical results compare very well with the theoretical solutions. The proposed numerical internal tank supplies one effective way for the numerical simulation of the interaction between the internal wave and the structure in the stratified ocean.
