摘要
采用ANSYS13.0自带DM模块构建空腔模型、MESH模块划分网格,以及FLUENT模块进行数值模拟,验证数值模拟的可靠性,进行计算分析.结果表明,在二维空腔模型中,利用机翼的升力原理,确能使产生垂直于漩涡来流的负阻力,该负阻力在x轴上的分量能达到减阻的目的.在不考虑三维模型的机翼及流水孔空腔宽度影响的情况下,初步计算减阻率在4.23%左右.
The DM of ANSYS13.0 is used to construct the cavity model, the MESH of ANSYS13.0 is to draw up the grid, and the FLUENT of ANSYS13.0 is used to numerically simulate the problem. First the reliability of numerical simulation is tested and verified, and then the calculation and analysis is done. Results show that the two-dimensional cavity model, using the wing＇s lift principle, can pro- duce negative resistance which is perpendicular to the spiral flow, the negative resistance on the x axis component can achieve the goal of resistance reduction. Without considering the width of the three di-mensional wing and water hole cavity, the preliminary calculating conclusion＇s resistance reduction rate is about 4.23 %.
