Developing an immersed boundary method for compressible flow

Abstract Development of a 3D sharp interface ghost node immersed boundary method (IBM) within fluid solver based on the compressible Navier–Stokes equations is underway. The objective IBM to accurately apply conditions at fluid–solid interfaces. currently being verified using various test cases, including classic cylinder in cross flow. As part this verification process, particular attention was given investigating effects different lateral conditions. results demonstrate that extrapolation exhibit better agreement with literature compared symmetry conditions, cases relatively narrow domains. These findings highlight potential benefits reducing confinement and removing nonphysical waves external flow problems.
