Abstract
The paper presents two computational techniques that do not require a change in the topology of the mesh to simulate the flow around oscillating bodies. The first technique uses the immersed boundary method, the second technique uses the method of deformed meshes. The capabilities of these two approaches are demonstrated by solving model problems in a two-dimensional formulation for simulating acoustic fields generated by an oscillating cylinder, both single and in the presence of a fixed cylindrical body, in a subsonic flow.中文翻译:
