Separate reconstruction and evolution steps are taken to discretize the convective terms. For the reconstruction step, a data-dependent Least-Squares procedure is used, while for the evolution step two recent flux functions are included: the HLLC approximate Riemann solver and the AUSM+ flux vector splitting. Steady-state solutions are obtained with an implicit backward Euler scheme. The assembled system is solved by iterative means (BiCGSTAB, GMRES) with ILU pre-conditioning.<\/jats:p>\n               <jats:p>Two internal, steady, 2D flow test cases are presented to validate the code: a supersonic 10\u00b0 ramp inside a channel and a laminar flow through a double-throated nozzle.<\/jats:p>\n               <jats:p>The code proved accurate with the use of both flux functions when comparing the computed results with both an analytical (ramp) and a reference solution (nozzle). The GMRES solver generally required less CPU time until convergence for the inviscid test-case while the BiCGSTAB solver got the edge for the viscous calculations.<\/jats:p>","DOI":"10.1115\/imece1998-0861","type":"proceedings-article","created":{"date-parts":[[2022,1,31]],"date-time":"2022-01-31T14:08:18Z","timestamp":1643638098000},"page":"351-360","update-policy":"http:\/\/dx.doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":1,"title":["Compressible Fluid Flow and Heat Transfer Navier-Stokes Predictions on Unstructured Grids"],"prefix":"10.1115","author":[{"given":"Nelson P.
