Immersed boundary method implemented for the simulation of an external flow on unstructured meshes

详细

A method is developed for the numerical simulation of an external flow around solid bodies of unstructured meshes. Several types of boundary conditions are set on the surface of the body, which are simulated by different modifications of the immersed boundary method. The method efficiency is demonstrated on 2D model problems on the computation of subsonic and supersonic flows around a cylinder.
