A Unified Method for Predicting the Performance of Subsonic Diffusers of Several Geometries

A unified performance prediction method was developed for class A diffusers. Class A diffusers have specified flow and geometry restrictions. The prediction method is a system of linear, first order differential equations. These equations embody the momentum equation, continuity equation, and two empirical correlation equations. In addition to the prediction method, two parameters were developed to characterize inlet conditions and separation respectively.
