WebMar 1, 2012 · 10.1.2 Forced Convection. In forced convection, the Nusselt number depends on the rate of heat transfer through a boundary layer from a surface hotter or cooler than the air passing over it, a process analogous to the transfer of momentum by skin friction. The Nusselt number is therefore expected to be a function of the Reynolds …
