摘要：

Results are given of experimental investigations of air flow in the vicinity of a vertical plate under stepwise heating which leads to inversion of heat flux on the surface. It is suggested to generalize to this case the algebraic model of turbulent thermal diffusivity developed by us previously. The results of calculations of such flow are compared with experimental data, and special features of the structure of thermal layer are identified.
