The Evaluation of Performance Losses in Multi-Dimensional Propulsive Flows

Abstract

A method for identifying and evaluating the thrust losses in an aerospace engine is first applied to onedimensional scramjet engine flows with coupled loss mechanisms. Overall engine thrust losses are related directly to local increases in irreversible entropy due to friction, heat transfer, mixing, non-equilibrium reaction, and shocks. This method is then extended to enable the evaluation of thrust losses in multi-dimensional flows. The fundamental relationship between performance assessment utilizing multidimensional flow-fields and cycle analysis performance prediction is shown and discussed.
