Heat-transfer in boundary-layer at a wall with a quasiperiodic temperature distribution

The system of determining equations describing the flow and heat transfer in a laminar boundary layer at a wall with a specified quasiperiodic temperature distribution is subjected to asymptotic analysis. The small parameters of the problem are taken to be the inverse of the Reynolds number and the ratio of the period of temperature variation of the wall to the wall dimension. It is shown, in particular, that the inhomogeneity of the gas temperature associated with inhomogeneity of the wall temperature is localized in a thin region at the wall and does not penetrate into the external region on account of convective drift.
