Engineering thermodynamics is a discipline, studying the heat transfer and conversion law between heat and other energy (especially mechanical energy). Through this course, the students can understand and master a new theoretical method system. Through the study, students can understand the scientific laws of energy conversion and energy effective utilization, establish the rational ideas of using energy, master the methods and means of analyzing problems about engineering thermodynamics, can apply these theories to the thermodynamic processes and thermodynamic cycles for proper analysis and calculation. Through careful study of the course, ultimately the theoretical foundation for the professional courses and work can be laid.
