Prediction of the Pressure Distribution of Mass Variable Flow in a Circle Distributor

Based on the principle of momentum balance, the one dimension mass variable flow in a circle distributor was analyzed, and a calculating formula of the pressure distribution of it in the circle passage was derived. Compared with that measured by experiments, the mean relative deviation of the pressure distribution predicted is no more than 5%, which implies that the method of this paper is suitable to analyze the one dimension mass variable flow in the circle distributor.
