Description
the branch of hydro aeromechanics that deals with the movement of compressible gaseous and liquid mediums and their interactions with solids. As a part of physics, gas dynamics is related to thermodynamics and acoustics.Thermal Engineering is a specialized sub-discipline of mechanical engineering and chemical engineering that deals with the movement of heat energy and transfer. The energy can be transformed between two mediums or transferred into other forms of energy.
