A thermal boundary layer develops if the fluid free stream temperature and the surface temperatures differ. A temperature profile exists due to the energy exchange resulting from this temperature difference. The heat transfer rate can be written using Newton's law of cooling as WebThe Nusselt number is the ratio of heat transfer by convection to the heat transfer by conduction within a fluid (When the fluid is considered stationary).

Nusselt numbers, velocity scales and boundary layer thicknesses are calculated.

WebIn fluid dynamics, the Nusselt number (Nu) is the ratio of convective to conductive heat transfer at a boundary in a fluid. Convection includes both advection (fluid motion) and diffusion (conduction). The conductive component is measured under the same conditions as the convective but for a hypothetically motionless fluid.
