Simulation of unsteady twodimensional inviscid flow fields around geometrically complex objects
Abstract
Numerical solutions are obtained for unsteady inviscid twodimensional flows around objects of complex geometric shape. The unsteady Euler equations are solved using an explicit finitevolume method based upon MacCormack's explicit method with fluxvector splitting. The equations are solved on a bodyfitted multizone computational grid that allows for discontinuous grid lines at zone interfaces and timedependent translation of a subset of the zones. The multizone solution procedure is implemented in a computer code called ZEUS/2D. This code is applied to several flows to validate and demonstrate the multizone solution procedure. The multizone solution procedure is shown to be useful and accurate for solving engineering problems with complex geometries.
