 Heat transfer may be a discipline of thermal engineering that issues the generation, use, conversion, and exchange of thermal energy (heat) between physical systems. Heat transfer is classed into varied mechanisms, like thermal physical phenomenon, thermal convection, thermal radiation, and transfer of energy by part changes. Engineers additionally take into account the transfer of mass of differing chemical species, either cold or hot, to attain heat transfer. Whereas these mechanisms have distinct characteristics, they typically occur at the same time within the same system. Heat physical phenomenon, additionally referred to as diffusion, is that the direct microscopic exchange of K.E. of particles through the boundary between 2 systems. Once associate object is at a special temperature from another body or its surroundings, heat flows so the body and also the surroundings reach identical temperature, at that purpose they're in equilibrium. Such spontaneous heat transfer continually happens from a section of heat to a different region of lower temperature, as represented within the second law of physics. Heat convection occurs when bulk flow of a fluid (gas or liquid) carries heat along with the flow of matter in the fluid. The flow of fluid may be forced by external processes, or sometimes (in gravitational fields) by buoyancy forces caused when thermal energy expands the fluid (for example in a fire plume), thus influencing its own transfer. The latter process is often called "natural convection". All convective processes also move heat partly by diffusion, as well. Another form of convection is forced convection. In this case the fluid is forced to flow by use of a pump, fan or other mechanical means.
