A hybrid method for unsteady inviscid fluid flow

2009 (English)In: Computers & Fluids, ISSN 0045-7930, E-ISSN 1879-0747, Vol. 38, no 4, 875-882 p.Article in journal (Refereed) Published
Abstract [en]

We show how a stable and accurate hybrid procedure for fluid flow can be constructed. Two separate solvers, one using high order finite difference methods and another using the node-centered unstructured finite volume method are coupled in a truly stable way. The two flow solvers run independently and receive and send information from each other by using a third coupling code. Exact solutions to the Euler equations are used to verify the accuracy and stability of the new computational procedure. We also demonstrate the capability of the new procedure in a calculation of the flow in and around a model of a coral.
