NON-STEADY-STATE HEAT TRANSFER OF FINNED SURFACE
Аннотация
For many purposes, the finned surface is being used to increase heat transfer. Heat exchangers and fuel elements of gas cooled nuclear reactors require the use of the finned surface for high flux heat transfer. In this paper, the problem is analytically treated by deriving a non-steady-state equation of radiative and convective heat transfer of annular and radial fins in case of sudden change of the fin-root temperature or heat flux. The numerical solution of temperature distribution along the fin is obtained for several typical transient cases.
