摘要
It can be purposeful to improve thermodynamics process and cycle if the exergy loss is divided into avoidable and inevitable exergy loss.A derived formula is presented to determine the inevitable exergy loss caused by heat transfer temperature difference based on steady-state continuum flow non-endoreversible Carnot cycle using finite-time thermodynamics.The inevitable exergy loss due to heat resistance in actual steam power plant can be calculated.The results obtained provide a general theoretical tool for the optimal design and operation of real cycle.
