摘要
在计入换热器热阻和压气机、涡轮中不可逆损失后，导出太阳能驱动变温热源闭式简单布雷顿循环功率、效率与循环压比关系的解析公式。
On the basis of the previous work by the authors in this journal[1]. the analytical formulas between power output. thermal efficiency and pressure ratio for an irreversible. closed-cycle, simple solar Brayton plant with variable temperature reservoirs are derived. Some irreversible losses. such as the heat resistance losses in the heat exchangers between working fluid and heat resorvoirs. the nonisentropic compression and expansion losses in compressor and turbine of the plant. are considered in the derivation of the formulas.
