Optimization Analysis of Ship Steam Power System with Finite-Time Thermodynamics Theory

摘要：

　　A basic model with both property of thermodynamic and heat transfer is obtained by simplifying the prime process of ship Steam Power System (SPS),which is converted into endoreversible Carnot Cycle by the introduction of mean temperature in the cycle process.The design parameters is analyzed and optimized in the view point of finite time thermodynamics (FTT) and entropy generation minimization.Results show that,the temperature ratio (α) and the heat transfer parameter ratio (β) of heat source and heat sink are two important influence factors of cycle system performance,and the increase of α and decrease of β will redound to the reduction of irreversible loss and enhancement of power output.
