✦ Synopsis

An improved Navier±Stokes solver is presented to compute two-dimensional incompressible ¯ows in the stream±vorticity formulation at high Reynolds number. The technique is based on both the IMM for the nonorthogonal co-ordinate system and a specialized TVD scheme to cope with non-linear transport terms. Numerical results are shown to demonstrate the accuracy and ef®ciency of the technique. The method is robust and holds promise to handle complex geometries economically.
