total heat transfer
1Heat transfer coefficient — The heat transfer coefficient, in thermodynamics and in mechanical and chemical engineering, is used in calculating the heat transfer, typically by convection or phase change between a fluid and a solid::Delta Q=h cdot A cdot Delta T cdot Delta… …
2Convective heat transfer — See also: Heat transfer and convection This figure shows a calculation for thermal convection. Colors closer to red are hot areas and colors closer to blue are cold areas. In this figure, a hot, less dense lower boundary layer sends plumes… …
3Enhanced heat transfer — Heat exchangers were initially developed to use plain (or smooth) heat transfer surfaces. An Enhanced heat transfer surface has a special surface geometry that provides a higher thermal performance, per unit base surface area than a plain surface …
4Radiosity (heat transfer) — In the fields of optics and heat transfer, radiosity is the total emitted and reflected radiation leaving a surface. The diffuse radiosity (J) is the integral of the hemispherical spectral radiosity (J {lambda}) over the spectrum::J = int… …
5Heat conduction — or thermal conduction is the spontaneous transfer of thermal energy through matter, from a region of higher temperature to a region of lower temperature, and acts to equalize temperature differences. It is also described as heat energy… …
6Heat flux — or thermal flux is a flow of energy per unit of area per unit of time. In SI units, it is measured in [W·m 2] . It has both a direction and a magnitude so it is a vectorial quantity. To define the heat flux at a certain point in space, one takes… …

8Heat exchanger — An interchangeable plate heat exchanger Tubular heat exchan …
9Heat — In physics, heat, symbolized by Q , is energy transferred from one body or system to another due to a difference in temperature. [cite book|author= Daintith, John |title=Oxford Dictionary of Physics|publisher=Oxford University… …
10Heat pipe — A heat pipe is a heat transfer mechanism that can transport large quantities of heat with a very small difference in temperature between the hotter and colder interfaces. Inside a heat pipe, at the hot interface a fluid turns to vapour and the… …
