Web5.0 Extended Surfaces Convection heat transfer from a solid surface to an adjacent fluid is limited by the area of the surface. It would seem reasonable, therefore, that if the surface area could be increased, an increase in heat transfer could be attained. This is done by adding fins to the surface. Heat is transferred by conduction along the fins and by … http://web.mit.edu/16.unified/www/FALL/thermodynamics/notes/node123.html

"Convection (or convective heat transfer) is the transfer of heat from one place to another due to the movement of fluid. Although often discussed as a distinct method of heat transfer, convective heat transfer involves the combined processes of conduction (heat diffusion) and advection (heat transfer by bulk fluid flow). Convection is usually the dominant form of heat transfer in liquids and ga… " - Fluid to fluid convection
