A COMPARISON OF UPWINDING AND SYMMETRY CONVECTION SCHEMES FOR THE RESOLUTION OF N-S EQUATIONS
This article presents a comparison of upwinding and symmetry convection schemes for the solution of the Navier-Stokes equations. The driven cavity flow problem at Reynolds number of 5000, 75000 and 10000 are solved by three different convection schemes, CD, QUICK and third order symmetry (TS), respectively. All the convection schemes are implemented on a uniform gird system with the grid density as high as The computed results with the TS scheme are compared with the benchmark solutions and those of CD and QUICK schemes in the averaged relative error and local relative error sense. It is found the TS scheme can provide more accurate results than the QUICK scheme at the same computation cost.
