Abstract: Based on immersed boundary conditions we build the numerical method of simulation of external flows around solid bodies on unstructured meshes. Two types of boundary conditions on the body surfase are implemented using different modifications of the method. The method efficiency is demonstrated on 2D model problems on subsonic and supersonic flow around a cylinder.

Keywords: numerical modeling, viscous flow, immersed boundary method, Brinkman penalization method, characteristic based volume penalization method.
