Thermal Boundary Layer

hi all. I'm curious as to whether you can theoretically work out the thermal boundary layer thickness of a flow over a heated flat-plate. freestream velocity is 5m/s aluminium flatplate surface temperature is 45c plate is 890mm long. area of interest is at location x=300mm is it possible? I want to find the theoretical…

hi all.

I'm curious as to whether you can theoretically work out the thermal boundary layer thickness of a flow over a heated flat-plate.

freestream velocity is 5m/s
aluminium flatplate surface temperature is 45c
plate is 890mm long.
area of interest is at location x=300mm

is it possible? I want to find the theoretical thermal bounhdary layer thickness, couple it with the Prandtl number, and hence find the momentum boundary layer thickness.

Thanks

I'd have to say yes there is a unique solution, finding it will be the hard part.

For a laminar flow both of these would be governed by the diffusion equation.

How good are you on PDE's?
