以创新的理念搞好热力学第二定律及其工程应用的教学

热力学第二定律是化工热力学核心教学内容之一,是工业装置用能标定和评价的基础,因此如何在本科热力学教学中说清热力学第二定律,掌握其工程应用方法显得尤为重要.作者根据多年的实际教学经验,从熵的基本概念、定性与定量表达方法出发,引申出熵产、理想功、损失功和有效能等基本热力学量,并将其应用于评价实际化工单元过程和装置组合.

Creative Ideas Help Thermodynamic Second Law Teaching and Application

Thermodynamic Second Law is the hard-core content of chemical engineering thermodynamics and the ratification and evaluation basis of energy consumption for industrial apparatus.Therefore,it is very important to expound clearly to the students the concept of the Second Law and master it.Based on the long-years' practical teaching experience,the author explains clearly the qualitative concept and quantitative expression of entropy.And then he deduces the concepts of entropy generated,Carnot circulation,ideal work,lost work,available energy and their balanced equations.He also makes application in energy evaluation for actual unit operation apparatus of chemical engineering or their combinations.
