In 2-D mathematical model, one of important problems is to improve computational speed. The multigrid method is a new rapid iteration method developed in the recent 20 years, and it has been widely used in many fields...
In this paper a new method for predicting the hydrodynamic performance of the flap rudder behind a propeller was presented. The hydrodynamics of the rudder was calculated by the panel method and the performance of the...
Based on the Homotopy Analysis Method, a direct numerical method for strongly nonlinear problems was proposed. The 2-D laminar flow over semi-infinite plate was used. The method can give the accurate enough approximat...
