Mechanical engineering including mechanical and chemical engineering. At its simplest, thermodynamics is the study of energy, its use and transformation through a system. Typically, engineering thermodynamics is concerned with changing energy from one form to another. As an example, automotive engines convert chemical energy (enthalpy) from the fuel into heat, and then into mechanical work that eventually turns the wheels. Thermodynamics principles are used by mechanical engineers in the fields of heat transfer, thermofluids, and energy conversion. Mechanical engineers use thermo-science to design engines and power plants, heating, ventilation, and air-conditioning (HVAC) systems, heat exchangers, heat sinks, radiators, refrigeration, insulation, and others.
Dalian University of Technology Dalian University of Technology Dalian University of Technology (DUT) (), colloquially known in Chinese as Dàgōng (大工), is a public research university located in Dalian (main campus) and Panjin in Liaoning, China. DUT, previously renowned as one of the Big Four Institutes of Technology, is among China's top universities for engineering and technology. It is a Chinese Ministry of Education Class A Double First Class University, and is also one of the national key universities administered directly under the Ministry of Education of China.
