Abstract:

In present paper the divergent and convergent characters of SIMPLE method are investigated by taking them as calculating examples, which the flow field in axisymmetric sudden expanding straight nozzle and sudden shrink-after-sudden enlargement nozzle. A reliable calculating method is proposed, which had been successfully used in the calculation for flow fields mentioned above.
