Taking power density; defined as the ratio of power output to the maximum specific volume in the cycle; as the objective function; this paper applies the theory of finite time thermodynamics to find the optimal distribution of heat conductance of the hot- and cold-side heat exchangers; the optimal intercooling pressure ratio; the optimal total pressure ratio and the optimal heat capacity ratio between working fluid and heat reservoir of an endoreversible closed intercooled regenerated Brayton cycle coupled to variable-temperature heat reservoirs with heat resistance losses in the hot- and cold-side heat exchangers; the intercooler and the regenerator; by using detailed numerical calculation. The maximum power density; the double-maximum power density and the triple-maximum power density are obtained by optimisation. The effects of some design parameters; including the cycle inlet heat reservoir temperature ratio; the inlet temperature ratio of cooling fluid in the intercooler and the cold-side heat reservoir; and the total heat exchanger inventory; on the maximum power density and the corresponding efficiency; optimum intercooling pressure ratio; and optimum heat conductance distributions between the hot- and cold-side heat exchangers; the double-maximum power density and the corresponding efficiency and optimum total pressure ratio; as well as the triple-maximum power density; are analysed. © Ambient Press Limited 2006;
