Numerical simulation for the low Reynolds number 3D flows around micro air vehicle

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.
