| Abstract: | On the basis of the previous work, this paper derived:(1)the analytical expressions between power output and efficiency as well as pressure ratio of irrevelsible closed Brayton power cycle under constant-temperature and variable temperature heat reservoirs conditions: (2)the optimum pressure ratios corresponding to maximum power and efficiency; (3)the optimum distribution of heat conductivities and matching between working fluids and variable-temperature heat reservoirs under given pressure ratios. |
