RESUMO
Local thermal disturbances generated by a small mechanical forcing on a curved surface are under consideration within the framework of the interacting boundary layer in the limit of large Reynolds number. Variations of the self-induced pressure and temperature are found to be explicitly related and an analytic solution of a linear perturbation analysis is presented. The heat flux associated with the selfinduced pressure may attain values comparable with the heat flux in the oncoming boundary layer. The analogy between the normal-to-wall vorticity and spanwise derivative of temperature is established.
