Thermal fluids

Thermofluids^[1]^[2] 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

chemical reactions

may also be important in a thermofluid context. The subject is sometimes also referred to as "thermal fluids".

Heat transfer

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.

Sections include :

Energy transfer

by heat, work and mass

Laws of thermodynamics
Entropy
Refrigeration Techniques
Properties and nature of pure substances

Applications

Engineering : Predicting and analysing the performance of machines

Thermodynamics

macroscopic variables, such as temperature, volume and pressure

, which describe physical, thermodynamic systems.

Fluid mechanics

Fluid Mechanics the study of the physical forces at work during fluid flow. Fluid mechanics can be divided into fluid kinematics, the study of fluid motion, and fluid kinetics, the study of the effect of forces on fluid motion. Fluid mechanics can further be divided into fluid statics, the study of fluids at rest, and fluid dynamics, the study of fluids in motion. Some of its more interesting concepts include momentum

and reactive forces in fluid flow and fluid machinery theory and performance.
