An implicit upwing algorithm for computing turbulent flows on unstructured grids. (English) Zbl 0806.76053
The authors present an implicit Navier-Stokes solution algorithm for the computation of turbulent flow on unstructured grids. The flux difference splitting of Roe is used for computing the inviscid contribution to the flux, and an implicit solver based on backward Euler time differencing is utilized for updating the solution. All developed algorithms are tested with numerical experiments.
