摘要：
In this paper we present the results of numerical modeling of nonlinear convection regimes in a square cavity filled with water solution of sodium chloride, which was done taking into account the polynomial temperature dependence of the thermal diffusion coefficient. We consider several variants of changing the temperature difference between the upper and lower walls, including the situation, in which the coefficient of thermal diffusion inside the cavity changes the sign. A comparison of the results of numerical simulation with those obtained in the case of a constant thermal diffusion coefficient showed that the influence of the temperature dependence of the thermal diffusion coefficient is small if the cavity is heated from below and causes convection if it is heated from above.
