摘要
考虑高低温侧换热器、回热器和中冷器的热阻损失,以及压气机和涡轮中的不可逆损失,以功率为优化目标,借助数值计算,研究了恒温热源条件下不可逆闭式中冷回热布雷顿循环输出功率最大时高低温侧换热器、回热器和中冷器的热导率分配以及中间压比与总压比的关系。
By detailed numerical calculations, the characteristics of the intercooling pressure ratio and the heat conductance distributions among the hot-and cold-side heat exchangers, the regenerator and the intercooler at the maximum power of an irreversible dosed intercooling regenerated Brayton cycle coupled to constant-temperature heat reservoirs are studied by taking the power as the optimization objective with consideration of the heat resistance in the hot-and cold-side heat exchangers, the regenerator and the intercooler and the irreversible losses in the compressor and turbine.
