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 Institute of Science and Technology Dalian Institute of Science and Technology Dalian Institute of Science and Technology (), is a four-year engineering college, located in Lüshunkou District, Dalian City, Liaoning Province, China. It has its origin in the Information Technology Department, established in 2002, of Dalian Jiaotong University, and became in 2003 an independent school owned by both Jiaotong University and Dalian Sunshine Century Group. It was renamed in 2011 as Dalian Institute of Science and Technology. It has now various departments, such as mechanical engineering, electrical engineering, information technology, software technology, foreign languages (English and Japanese) and fine arts.
