Simulation of Amphibious Vehicle Water Resistance Based on FLUENT

Amphibious vehicle shape changing shape structure, compared with the hull, its water resistance factors more and more computationally complex. Calculated using the traditional theory it is difficult to accurately estimate their water resistance force and distribution. In this paper, the water resistance FLUENT software simulation analysis can more accurately calculate and analyze the water Amphibious Vehicle force distribution. This paper has established amphibious vehicle CFD models, set the environmental parameters and boundary conditions, the amphibious vehicle water resistance characteristics were simulated. Amphibious vehicles obtained two-phase distribution of water vapor, the body and the body surface pressure distribution free surface profile, the final calculation of the amphibious vehicle water resistance values.
