Interacting boundary layers and heat transfer

The application of triple deck analysis to heat transfer for an incompressible flow disturbed by a dent under the boundary condition of constant wall temperature is addressed. No disturbance of temperature is found in the upper deck, because the energy equation contains no term equivalent to the pressure term of the momentum equation which is responsible for the pressure change in the upper deck. The temperature profile in the main deck behaves quite similarly to the velocity profile, being shifted outward by the same amount as the velocity profile without further change. The asymptotic structure of the flow field, the wall shear distribution in the recirculating case, and the heat transfer in the dent region for the recirculating and nonrecirculating cases are depicted.
