ON STRATIFIED FLOWS CAUSED BY SPATIAL INHOMOGENEITIES OF TRANSFER COEFFICIENTS

The previously unstudied mechanism of the emergence of stratifi ed fl ows caused by spatial inhomogeneities of exchange coeffi cients is investigated analytically. In the calculations, a linear approximation is used with specifi ed horizontally harmonic variations of the thermal conductivity coeffi cient of a relatively small amplitude. Explicit analytical expressions are obtained for temperature perturbations of the environment and velocity of fl ows in it. The possibility of intensifying such perturbations for some values of the medium parameters is shown.
