摘要：
The completely implicit method for unsteady SIMPLE algorithm was utilized to study some problems such as the unsteady flow between two counter-rotating rotors, especially the influence on flow field made by the wake flow of upstream and potential affection of downstream. Compared with dynamic experimental results, the numerical simulation for unsteady flow is more suitable for the actual characters of turbomachinery and there would be more increment on the pressure rise and higher efficiency if the structure of unsteady flow in counter-rotating fan is organized well.
