Abstract

"Recent analytical advances in understanding the performance range (thermodynamic spectrum) for air-breathing engines based upon fundamental second-law considerations have clarified scramjet and ramjet operation, performance, and characteristics. Second-law based analysis is utilized extensively in this work to clarify and describe the performance characteristics for dual-mode scramjet operations in the mid-speed range of flight Mach 4.0 to 7.0. This is accomplished by a fundamental investigation of the complex but predictable interaction between heat release and internal irreversibilities in such an engine...In addition, an irreversibilty auditing method is formulated to extract the lost performance potential associated with the different loss mechanisms (losses due to friction, heat transfer, mass diffusion, finite-rate kinetics, and shock waves) associated with a given flow-field"--Abstract, page iii.
