A Hybrid Method for Unsteady Fluid Flow
Show others and affiliations
2007 (English)Report (Other academic)
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 andanother using the node-centered unstructured finite volume method are coupled ina truly stable way. The two flow solvers run independently and receive and sendinformation from each other by using a third coupling code. Exact solutions to theEuler equations are used to verify the accuracy and stability of the new computationalprocedure. We also demonstrate the capability of the new procedure in acalculation of the flow in and around a model of a coral.
