Hello,

For thermal boundary layer over a flat plate normally in the books the plate is assumed to thin ie with negligible thickness. even for flat plates with thickness, the leading edge is chamfered in way so that flow first sees the pointed corner.

I am running a simulation with thick flat plate with blunt leading edge and was wondering if the thermal boundary layer will start just at the blunt leading edge or slightly ahead it. Since Stagnation point will be present at the blunt LE i suppose the Thermal BL should start little ahead of the blunt LE. Isothermal BC is given for flat plate, flow is laminar steady and incompressible.

Any input, suggestion is most welcome.

Thanks

standard BL theory cannot consider the point x=0 as it is singular for the field...

Thanks a lot for the valuable information ...
