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 Minzu University Dalian Minzu University Dalian Minzu University () is located in Dalian, Liaoning, People's Republic of China and directly supervised by the State Ethnic Affairs Commission. Dalian Minzu University was founded in 1997. As the only Nationalities University focusing on technology and applied science, it has grown very rapidly ever since. It is now one of the leading universities in Northeast China. Students of DLNU have won numerous awards in various scientific and technological competitions, including winning Mathematical Contest in Modeling (MCM) 2005, representing China to compete in Robocup 2007, Winning Microsoft Imagine Cup in China 2008 and Second Price internationally
