Abstract

This paper presents a performance analysis and optimization for irreversible Brayton cycle based on the Ecological Coefficient of Performance (ECOP) criterion. The ECOP objective function is defined as the ratio of power output to the loss rate of availability. The maximum of ECOP and performance parameters are derived analytically under the assumption of optimal design. The graphical representations of the developed ECOP function in terms of governing parameters are discussed in detail. The effect of dominant parameters on optimal ecological performances has been investigated. The comparisons of ECOP, dimensionless ecological function and power output with respect to the dimensionless entropy generation rate and the enthalpy ratio are presented.
