Churchill and bernstein equation
http://fchart.com/ees/heat_transfer_library/external_flow/hs90010.htm WebThe general definition of the heat transfer coefficient is: where: q: heat flux (W/m 2 ); i.e., thermal power per unit area, q = d Q ˙ / d A {\displaystyle q=d {\dot {Q}}/dA} ΔT: difference in temperature between the solid surface and surrounding fluid area (K) The heat transfer coefficient is the reciprocal of thermal insulance.

WebNusselt number. In thermal fluid dynamics, the Nusselt number ( Nu, after Wilhelm Nusselt [1] : 336 ) 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 ...
