摘要：

This paper presents a modified Goda scheme in the simulation of unsteady incompressible Navier-Stokes flows in cylindrical geometries. The study is restricted to the case of axisymmetric flows. For the justification of the robustness of our scheme some computational test cases are investigated. It turns out that by adopting the new approach, a significant accuracy improvement on both pressure and velocity can be obtained relative to the classical Goda scheme.
