AbstractThe overset grid approach provides a very powerful means of handling complex geometries in computational fluid dynamics. The overset grid approach has many practical benefits for unsteady moving grid simulation or rudder angle. Therefore an overset unstructured grid method was newly developed for an arbitrary polyhedral compressible flow solver, LS-FLOW. We set the IBlank for visualization and post-processing. In order to test the validity of the suggested methods, a numerical simulation was carried out on the NACA0012 airfoil.And our results are compared with experimental data and other CFD results. Furthermore, in order to evaluate the validity of this method, we also simulated the flow around a reusable sounding rocket under research at JAXA//ISAS. The result of the overset grid method corresponds with the result of the single grid method in the NACA0012 airfoil and the reusable sounding rocket. The good coincidence validates our newly deve""" loped overset grid method, and intend to use LS-FLOW as a design tool.
