Thermal fluids

Thermofluids is a branch of science and engineering encompassing four intersecting fields: Thermofluids is a branch of science and engineering encompassing four intersecting fields: The term is a combination of 'thermo', referring to heat, and 'fluids', which refers to liquids, gases and vapors. Temperature, pressure, equations of state, and transport laws all play an important role in thermofluid problems. Phase transition and chemical reactions may also be important in a thermofluid context. The subject is sometimes also referred to as 'thermal fluids'. Heat transfer is a discipline of thermal engineering that concerns the transfer of thermal energy from one physical system to another. Heat transfer is classified into various mechanisms, such as heat conduction, convection, thermal radiation, and phase-change transfer. Engineers also consider the transfer of mass of differing chemical species, either cold or hot, to achieve heat transfer.
