某水下机器人阻力特性的数值模拟
Numerical simulation of the resistance character of an underwater vehicle
摘要
Abstract
In this work,the computational fluid dynamics(CFD)method is used to study the resistance character of an underwater vehicle in a specific undersea tunnel circumstance.In order to prove the valid-ity of the proposed method,the standard Suboff model was numerically calculated and the simulation re-sults were in agreement with the experimental data published by ITTC.This work presents different effects of resistance and pressure on two front supporting structures with the simulation results of the two different models.The flow field around the vehicle and the resistance characteristics changing under different working conditions were analyzed.The results show that the bar supporting structure can reduce the re-sistance and surface pressure fluctuation compared with the board model and the trend of resistance and pressure changes under different working conditions is different.In the downstream direction,the resist-ance decreases with the increase of navigation speed,where in the upstream direction it goes by contra-ries.关键词
