Heat transfer is a discipline of thermal engineering that refers to the generation, use, conversion and exchange of thermal energy (heat) between physical systems. Heat transfer is classified into various mechanisms, such as thermal conduction, thermal convection, thermal radiation and energy transfer due to phase changes. Engineers also consider mass transfer of different chemical species, either cold or hot, to achieve heat transfer. Although these mechanisms have different characteristics, they often occur simultaneously in the same system.
Heat conduction, also called diffusion, is the direct microscopic exchange of particle kinetic energy across the boundary between two systems. When an object is at a temperature different from that of another body or its environment, the heat flows so that the body and the environment reach the same temperature, at which point they are in thermal equilibrium. Such spontaneous heat transfer always occurs from a region of high temperature to another region of lower temperature, as described in the second law of thermodynamics.

Heat convection occurs when the bulk flow of a fluid (gas or liquid) transports heat along with the flow of matter in the fluid. Fluid flow can be forced by external processes, or sometimes (in gravitational fields) by flotation forces caused when thermal energy expands the fluid (for example, in a fire plume), which influences its own transfer. The last process is often called "natural convection." All convective processes also move heat partly by diffusion. Another form of convection is forced convection. In this case, the fluid is forced to flow through the use of a pump, a fan or other mechanical means. The thermal radiation is produced through a vacuum or any transparent medium (solid or fluid). It is the transfer of energy by means of photons in electromagnetic waves governed by the same laws.
