In view of the speed of the wheeled amphibious vehicle s hipping on the water

numerical simulation of flow field was presented

making u se of k-ε turbulent model and VOF two-phase flow model based on the Fluen t platform

the sailing resistance variation of the amphibious vehicle was got. By comparison with the result of model of dragging experiment

the result of num erical simulation is confirmed

which is in line with the law of the resistance of drainage amphibious vehicles

and provides the reference for the structural o ptimization

resistance reduction and speed increasement of wheeled amphibious v ehicles.
