Abstract:
Schemes with nonlocal approximations (compact and multioperator) are used in the immersed boundary method. Their accuracy and convergence are analyzed in the case of a model problem. For the flow over a cylinder, the numerical results based on the compressible Navier–Stokes equations are compared with available numerical and experimental data. The cases of low, moderate, and high Reynolds numbers are considered.
Key words:
immersed boundary method, compact and multioperator schemes, radial basis functions, the Navier–Stokes equations, flow around a cylinder.
