摘要

In this paper, a viscous correction on LU-SGS method is applied to improve the stability and efficiency for incompressible viscous flows with pseudo compressibility. The viscous correction is implemented by stability analysis considering the contribution of the viscous jacobians. Several illustrative examples of incompressible flows over airfoils are computed with Reynolds number ranging from 103 to 106. The numerical results are in reasonably good agreement with experimental data and other research's computational results. It shows that the present method is stable and efficient for simulations of low Reynolds number flows.
