Aiming at hydrodynamic performance prediction for hydroplane longitudinal motion, numerical simulation for a hydroplane motion was carried out by using VOF and RNG k-ε model and solving Navier-Stokes equation under FLUENT software platform. Evolution of ship resistance was obtained as the velocity change, and flow field situation and dynamic pressure variation of hydroplane hull bottom were reflected intuitively. By comparing and analysing the results among numerical simulation calculation and ship model experiments and theoretical estimation, it was verified that hydrodynamic performance prediction for hydroplane longitudinal motion based on numerical simulation calculation under FLUENT is feasible and precise enough.
