core inlet flow rate 堆芯进口流速
The flow field of the core engine inlet was numerically calculated to solve the problem that the air flow measured in the air simulated test facility was inconsistent with ground test.
针对某型核心机地面台和高空台试验中空气流量测量不一致的问题，开展了核心机进口流场的数值计算分析和试验研究。
The results of the simulation indicate:compared with cyclone in other domain, the secondary flow of the preheating cyclone with pentagonal inlet and three core volute structure is relatively weaker.
模拟计算结果表明：与其他领域应用的旋风分离器相比，五边形入口、三心大涡壳式旋风预热器内筒入口附近次级流动相对较弱；
