Abstract

Abstract

The downstream flow of inlet model can be translated into multiple regions by the distributed flow regulator which is composed of two sets of guide vanes. The mass flow is regulated by adjusting the relative position which changes the flow area between the two sets of guide vanes. Two simplified models of the distributed regulator and throttle cone are simulated by commercial software and improved in FL-24 wind tunnel. It is shown that the distributed regulator owns good flow and regulating capacities. Owing to the technology of distributed flow regulator, the size of the flow-meter can be decreased. The results from the distributed regulator are in good agreement with ones from the throttle cone when there is no surge emerging. Also it has little effect on the whole flow field, especially on the upper flow.
