The paper presents a method for simulating the flow of a viscous compressible gas around a moving body on a simply connected unstructured mesh which is possible thanks to using the immersed boundary method, and the features of its application for computing the flow around a rotating propeller in two-dimensional formulation. An important part of the method is the adaptation of a moving mesh, that retains its topology, to the surface of the streamlined body. The position and shape of the body are set by the interpolation grid, which stores the distance to the body surface, and the normal to the surface. The technique is used to simulate the flow around a rotating propeller in a flow in twodimensional formulation. The shape of the propeller has areas of high curvature that requires a special approach when adapting to the boundaries. The paper presents the results of simulating the flow around a rotating propeller, as well as a few auxiliary problems considered to verify the developed method.
