Abstract:

This report describes the analytical work done on the Naval Academy Heat Balanced Engine NAHBE combustion Process. The purpose of this one year study is to investigate the proposed utilization of pressure exchange mechanism and the basic nonsteady flow processes and combustion phenomena associated with the NAHBE combustion system, utilizing the experimental test data obtained over a period of years at the U.S. Naval Academy, Annapolis. A preliminary analysis of the effect of pressure exchange on the performance of the NAHBE engine is given in reference 5 based on the volume mode approach. A front mode approach is assumed to construct a wave diagram as a first step towards an understanding of the nonsteady flow dynamics of NAHBE combustion system. Further, two simple heat release models are used to obtain expressions for pressure and the results compared with experimental NAHBE test data. Author
