A Scramjet/Ramjet Heat Exchanger Analysis Tool (SRHEAT) has been developed for rapid analyses of complex thermal cooling systems. The detailed heat exchanger design features included in this code (i.e. geometry, material properties, fuel/coolant properties, etc.) make SRHEAT a valuable tool in scramjet and hypersonic vehicle development, providing the low cost analytical capabilities that make possible the efficient development of aerospace components. A key feature of SRHEAT is its ability to optimize the heat exchanger thermal design for minimum fuel flow requirement while providing a structurally viable design. Optimization includes both the ordering of the cooling flow circuit and the sizing of the heat exchanger channels. Large computational times are required for standard optimization techniques due to the sheer number of interdependent variables associated with the complex thermal management system. Several methods have been developed and adapted to reduce computational time requirements of optimization. The result is a fast code with the built-in intelligence to make design decisions leading to an optimized thermal management system design. |
