针对2k70型轴流式通风机从集流器进口到扩散器出口的内部三维全流场做了定常的数值模拟。

A numerical simulation of the three-dimensional steady flow field in the whole flow field, from the inlet of the collector to the outlet of the diffuser, a 2k70 axial-flow fan is performed.

采用C-H型网格、守恒型非定常全位势方程的时间精确近似因式分解差分法计算二维、三维的跨声速非定常位势流。

The conservative full potential equation and C H grid are used to compute the unsteady transonic flows around airfoils and wings.
