The Nusselt number is the ratio of convective to conductive heat transfer across a boundary. The convection and conduction heat flows are parallel to each other and to the surface normal of the boundary surface, and are all perpendicular to the mean fluid flow in the simple case. where h is the convective heat transfer coefficient of the flow, L is the characteristic length, and k is the thermal conductivity of the fluid.

The Reynolds number is chosen (400), heat flux (2000 W/m2), Rayleigh number (1×105) and volume fraction concentrations (2.5 Vol %). The simulation is … WebPrandtl Numbers of most gases are close to unity (IJ rv 0.75), so the Reynolds analogy is approximately correct up to the wall even though the flow is laminar close to the wall. The first extensions of the application of Reynolds analogy to fluids with Prandtl Numbers differing from unity were made by Taylor2 in 1919 and PrandtP in
