摘要
利用"N S方程+粒子仿真"方法来计算含裂纹翼柱型装药内流场。计算结果表明:环形裂纹内的流动对主流的影响大于纵向裂纹,环形裂纹内上游位置流动对主流的影响较下游位置的大,并可保持到喷管喉部,翼槽附近环形裂纹内的流动对主流的影响相对较弱。
The inner flow field in finocyl grain with cracks is calculated by using the method of NS equation plus particle emulatoin. The results demonstrate that the influence brought about by flow in annular cracks on mainstream is more important than that in axial cracks. The influence by upstream flow is more significant than that of the downstream flow in annular cracks, and extends to the nozzle. The flow in annular cracks near the finslots has less impact on the mainstream.
