We present a symplectic analytical method for the study of two-dimensional low Reynolds number flow in a wedge-shaped cavity caused by constant unit tangential velocity of the curved wall.

After giving a brief summary of the development of ship CFD (computerised fluid dynamics) in recent years, the paper discussed in detail the latest development of relevant technologies such as mess generation, turbulence mode, free surface flowing, parallel calculation and high Reynolds number flow.

In order to solve several basic problems of high Reynolds number flow computations, we suggest a theory of strong viscous flow, where there exists at least one viscous term being the same order of magnitude as the inertial term in the Navier Stokes (NS) equations.
