Roe upwind method
Did you know?
Web1 Jun 1996 · An upwind numerical method for a six equation two-fluid model is presented based on a linearized Riemann solver. The construction of this approximate Riemann solver uses an extension of Roe`s method that has been successfully used to solve gas dynamics equations in aerodynamics problems. As far as the two-fluid model is hyperbolic, this ... WebFor this test case, we chose the Roe upwind scheme with 2nd-order reconstruction (MUSCL_FLOW = YES). Note that, in order to activate the slope limiter for the upwind methods, SLOPE_LIMITER_FLOW must be set to something other than NONE. For turbulent convective and viscous fluxes, the default schemes are the scalar upwind method and the ...
WebRoe's algorithm solves exactly a linearised problem, instead of looking for an iterative solution of the exact original Riemann problem. The approximate solver proposed by Roe is much less expensive in terms of computational effort than the exact one, because the exact solution of a linear Riemann problem can be more easily built. http://article.sapub.org/pdf/10.5923.j.ijhe.20140301.02.pdf

Numerical experi-ments on scalar conservation laws and the one dimensional shallow water equations show much better resolution of the steady state than the conventional method, with almost no new numerical complexity.
