摘要
本文建立了一种嵌套网格无重叠物面网格生成技术与气动力积分技术,该技术通过对物面网格iblank判定与标识,在重叠区域形成洞点,并通过三角形单元填充的形式建立封闭气动力积分面网格,气动力积分是在这种面网格上进行的压力与黏性应力的积分,并给出了气动力积分计算方法。最后通过典型数值实验验证了该方法计算结果的正确性。
In the paper,a water tight non overlapping body surface grid generation technique and aerodynamics integration method based on chimera grid is constmcted.by blanking the body surface grid,hole is generated in the overlapping zone,then triangle surface grid is constructed about the hole place,aerodynamics force and moment is integrated on the water-tight body surface.Numerical tests indicated that the method constructed by the paper is effective and have a good accuracy.
