Research on sliding hydrodynamic performance of flying boat

Abstract

The towing tank test of a scaled flying boat model is designed to obtain it’s resistance, heaving and pitching characteristics as the speed changes in the sliding progress; then based on the secondary development of fluent; the global moving mesh and VOF methods are applied in the simulation; the calculation gives the fluid field around the boat, especially the wake flow, and also the pressure distribution of boat step. the results compared to the experiment date prove that using this method to study the hydrodynamic performance of a flying boat is feasible and precise.
