基于CFX的全垫升气垫船船身空气动力模拟
Aerodynamic simulation of air cushion vehicle body using CFX
摘要
Abstract
A three-dimensional model of air cushion vehicle was established according to the threedimensional numerical simulation software Solidworks.Its flow field was also simulated numerically by ANSYS CFX software for computational fluid dynamics.Corresponding aerodynamic coefficients in the situations of different attack angles and drift angles were calculated.Effects of the varied aerodynamic coefficients by attack and drift angles were discussed.Numerical results show that with the drift angle increasing,the lateral force also increased; when the drift angle reaches 90°,the lateral force goes its maximum; with the drift angle increasing,the resistance reduces,when the drift angle reaches 90°,the drift become 0°; and the drift angles continue to increase,the resistance is positive,the lateral force and lift increase significantly,which will seriously affect the stability of the air cushion vehicle navigation.The simulation results were compared with experimental data and it is found that the calculated and experimental values are in good agreement.CFX software's applicability and reliability in cushion vehicle aerodynamics simulation were verified.关键词
