Convection, conduction, thermal radiation, and evaporative cooling are all examples of heat transport methods.
Heat has the unit joule (J) in the International System of Units as a kind of energy (SI). However, the British thermal unit (BTU) and the calorie are frequently employed in technical applications. The watt (W), which is defined as one joule per second, is the standard unit for heat transfer rate.
A coefficient of heat transfer (COP) is a measure of how efficiently heat is transferred from one object to another in an adiabatic, isentropic process.
Heat transfer is a natural phenomenon that can be used in many creative ways. It can be used to heat things, to cool them down, or even as an artistic medium. This application of heat transfer can be found in our homes, cars, and industries.
The core ideas of heat transfer: conduction, convection, and radiation are introduced in Fundamental Principles of Heat Transfer.
