Overview Overview of heat transfer Heat flows across temperature differences. There are three modes of heat transfer: conduction, radiation, and convection. Conduction and radia-tion are fundamental physical mechanisms, while convection is ...

Description of natural convection


... and an upward near-wall motion will be induced. Natural convection velocities are relat-ively gentle and the resultant wall heat flux will generally be less than in forced motion. [from White, Frank M., Heat Transfer ]

Description of radiation


Description of radiation Radiation In conduction and convection, heat flux is caused by local temperature gradients in the solid or fluid medium. Heat flux via radiation is different, dep-ending neither on a transfer medium nor on a temperatu ...

Description of conduction


... in the case of metals by drift of free electrons through the lattice. Thus, good electrical conductors are also good heat conductors. Both the molecular and the free-electron inter-actions are well founded in theoretical atomic physics. ...
