Minimization of entropy generation of a closed Brayton cycle based precooling-compression system for advanced hypersonic airbreathing engine
Xuanfei Yu,Cong Wang,Daren Yu +2 more
TL;DR: In this paper, a conjugated optimization coupled with heat exchanger design was performed to evaluate the performance level that can be achieved under the state of technologies, and the results indicated that irreversibility of the precooling-compression system (PCS) can be reduced but at the penalty of heavier and larger size of heat exchangers.
