Someone has already solved the Continuity, Navier-Stokes, and Energy equations to determine the temperature profile equation within the thermal boundary layer (with thickness d) for forced convection of air across a horizontal surface: 3 T(y) = 20 + 60. { - ( ) + + () } C 2 2 y is the vertical distance from the surface (y=0 at surface, and y=8, at the top of the thermal boundary layer). The units on the above equation are C. What is the film temperature for this problem? At some distance x along the plate the boundary layer thickness is & = 3mm. What is the heat flux at the surface at this location? Don't use Nusselt correlations to calculate. To To X Free-stream 18 Too Thermal boundary T layer T, +0.99(T-T)
