Engineering thermodynamics is a classical subject that studies the conversion of thermal energy and mechanical energy and the effective utilization of thermal energy. It is not only an important professional basic course for energy engineering, power engineering, mechanical engineering, aerospace, engineering thermophysics, building environment and equipment engineering, chemical engineering, and nuclear engineering, but also the theoretical basis of energy saving and the basis of heat utilization, heat design, heat management, and heat control foundation.

This is an edX course of "engineering thermodynamics" (National Excellent Course, 64 class hours) of Tsinghua University. Considering the differences in the basic knowledge of the learners outside the university, the edX course is divided into two parts: Engineering Thermodynamics (I) mainly includes basic concepts, the First Law of Thermodynamics, the Second Law of Thermodynamics, the properties and process of ideal gas and gas power cycle, etc; Engineering Thermodynamics (Ⅱ) mainly includes the properties and processes of real gas, steam power cycle, refrigeration cycle, wet air, the differential equation of thermodynamics, fundamentals of chemical thermodynamics, as well as some brief introductions of the research frontier and research application (as an extension of the course, marked with *, not included in grades), etc.

"Engineering Thermodynamics" is the science that studies the mutual conversion of thermal energy and mechanical energy and the effective utilization of thermal energy. It is an important textbook for majors such as energy engineering, power engineering, mechanical engineering, aerospace, engineering thermophysics, built environment and equipment engineering, chemical engineering and nuclear engineering. Professional basic courses are the theoretical basis of energy conservation, as well as the foundation of heat utilization, thermal design, thermal management and thermal control.

This course is an edX course of Tsinghua University's " Engineering Thermodynamics " ( National Quality Course ) physical course (64 hours ) . Considering the large differences in the foundation of students outside the school, the Engineering Thermodynamics edX course is divided into two parts: "Engineering Thermodynamics ( Part 1 )"》Mainly covers basic concepts, the first law of thermodynamics, the second law of thermodynamics, the properties and processes of ideal gases, and gas power cycles; while "Engineering Thermodynamics ( Part 2 ) " mainly covers the properties and processes of actual gases, steam power cycles, Refrigeration cycle, humid air, thermodynamic differential relations, basics of chemical thermodynamics, and expanded content such as subject research frontiers and introduction to research applications ( marked with * , no assessment requirements ) , etc.
