...C. V. Ramesh There is immense scope for the development of heat engines that can directly convert solar and biochemical renewable sources of thermal energy to high-grade energy. Regenerative Stirling cycle heat engine with its performance criteria of highest thermal efficiency and high mean...

...Yingru Zhao; Bihong Lin; Jincan Chen An irreversible cycle model of the Otto heat engine is established, in which the temperature-dependent heat capacities of the working fluid, the irreversibilities resulting from the nonisentropic compression and expansion processes, and heat leak losses through...

... in optimum cycle performance. In general, the KCS11 has better overall performance at moderate pressures than that of the organic Rankine cycle. 03 05 2006 24 02 2007 geothermal power heat engines ammonia heat exchangers Kalina cycle system (KCS11) ammonia isobutane Rankine...

...Yue Zhang; Congjie Ou; Bihong Lin; Jincan Chen An irreversible cycle model of the Brayton heat engine is established, in which the irreversibilities resulting from the internal dissipation of the working substance in the adiabatic compression and expansion processes and the finite-rate heat...

... power/cooling cycle and ( b ) cascaded cycle An analogy to the combined cycle is a cascaded power and refrigeration cycle, where part of the work output is directed into a refrigeration machine to obtain cooling. If the heat engine and refrigeration machine were to be treated together...
