空中加油吊舱尾流场计算分析

Computation and analysis of wake flow field of aerial refueling pod

为了得到空中加油吊舱尾后流场的分布特性,采用数值模拟方法对某型吊舱尾流场特性进行了仿真计算,分析了飞行高度和速度对加油吊舱尾流场分布的影响,并对计算结果进行了验证。研究结果表明,高度的变化对流场中速度矢量和涡量分布的影响较小,速度的变化对静压速度矢量和涡量的分布影响较大。

In order to obtain wake flow field behind aerial refueling pod,the paper adopts numerical simulation method to analyze the wake flow field which is behind a certain type of aerial refueling pod. Also,the paper gives the impact on flight height and velocity on wake flow field behind refueling pod; meanwhile it verifies the computational results. The computational results show that the height variation has less impact on velocity vector distribution and vorticity distribution,the velocity variation has a great impact on static pressure and velocity vector distribution and vorticity distribution.
