摘要：

Amphibious vehicle is too complicated to predict flow field around it. Computational fluid dynamics provide a new path for solving the problem. Flow field around vehicle is simulated based on Reynold averaged Navier-Stokes equations associated with Shear Stress k-w turbulence model and Volume of Fluid scheme. Governing equations are discretized by finite volume method, SIMPLE method is used for pressure correction, G-S is used for solving algebra equations. As a primary index for power performance, simulated value of resistance is compared to the value from experiment, relative error is about 5%. Resistance vs. velocity model is built and parameters in it are identified by least square method. Conclusion, wave resistance is proportional to 1.88th power of velocity, friction resistance is proportional to 1.76th power of velocity, shape resistance is proportional to 3.54th power of velocity. Hydro-power performance of amphibious vehicle can be qualitatively analyzed by means of this model.
