| 摘 要： | 针对当前所研究的微型飞行器(MAV)流动特征,采用时间相关法和有限体积法求解N-S方程,选择了Van Albada插值限量因子的高分辨率空间差分格式,建立了模拟MAV三维低雷诺数流场的数值计算方法。通过熵校正技术改进和粘性计算准确性与网格密度关系的分析,确保了流场计算的准确可靠。使用该数值算法,对某常规气动布局的MAV进行流场模拟和分析,并比较了其流场与常规尺寸飞行器的不同。

| Abstract: | The low Reynolds number 3D flows around Micro Air Vehicle(MAV) were simulated by solving N-S equations.The numerical solution includes time marching,finite volume method,and high resolution scheme.This investigation applied the Van-Albada limiter for interpolation,improved the entropy correction in upwind flux computation,and constructed the rule to judge if grids are enough fine to compute the viscous effects exactly.The difference of flows,around MAV and around a large one,was studied by using such numerical solution. |
