Numerical Study of Single-Mode Interface Shape on Rotary Motion Instability

Abstract:

Using the method of numerical simulations to study fluid dynamic characteristic of underwater vehicle rotary motion, using the N-S equation turbulence model description of the steady rotation of the vehicle, this paper studies the numerical calculation method of aircraft rotating derivative underwater, using UDF programming to produce a stable pressure rotation the flow field, set up an numerical turning basin. Then based on the simulation analysis the influence of the different radius of gyration and different angle of attack on the vehicle motion.
