Maximum Work and Efficiency of an Irreversible Regenerative Stirling Cycle | Chapter 12 | New Trends in Physical Science Research Vol. 1

 On a stationary irreversible regenerative Stirling cycle model, the effect of two sources of irreversibilities (limited rate of heat transfers and heat leak) is investigated. The purpose of this study is to figure out how to get the partial optimization criterion specified in [1]. Because when two design rules are used alternately: internal thermal conductance fixed, or regions fixed, the ideal relations for the allocation and efficacy of the heat exchangers of the Stirling power plant are established. These optimal relationships are the same for optimum particular power and efficiency. By inserting these optimal values in the specific power and efficiency, for example, the greatest specific power and efficiency can be found. When the maximum efficiency and specific power are evaluated, it is observed that the maximum efficiency is greater than the maximum particular power under both design rules. When the design rule is bound by the set areas of the heat exchangers, the efficiency is higher.

Maximum Power and Efficiency to Maximum Power for a Power Plant with n Carnot-Like Cycles | Chapter 3 |New Ideas Concerning Science and Technology Vol. 13

 The performance of a stationary power plant with n Carnot-like cycles is optimized. The following irreversibilities exist in each cycle: finite rate heat transfers between the working fluid and external heat sources, internal dissipation of the working fluid, and heat leak between reservoirs. In a previous study, [1] the optimal allocation or effectiveness of the heat exchangers for this power plant were determined by applying two design rules, alternatively:internal thermal conductance fixed or fixed areas In this work, the obtained optimal relations are substituted in the power and the maximum power is calculated, with respect to the isentropic ratio of each of the power plant's Carnot-like cycles and for both design rules (using only the law of heat conduction). In addition, the efficiency to maximum power is shown.
