Abstract: | The solution of the conjugate problem of convective-conductive heat transfer in the channels of power plants is presented.
The problem of convective heat transfer in the gas phase is solved by the integral theory of heat transfer. A one-dimensional
problem of conductive heat transfer in the material of the wall is solved by the finite-difference method. Relative laws of
heat and mass transfer and friction are obtained by numerical integration with respect to the boundary-layer thickness. The
effect of the material and geometry of the wall on the level of problem “conjugation” is studied.
