Convection of a Binary Mixture with Thermal Diffusion Coefficient That Depends on Temperature

In this paper we present the results of numerical simulation nonlinear regimes a NaCl aqueous solution in square cavity with rigid and impermeable for substance boundaries. The vertical boundaries are thermally insulated, there different constant temperatures on horizontal ones, it corresponds to heat from below. calculations carried out within non-stationary approach, using Boussinesq approximation taking into account polynomial dependence thermal diffusion coefficient temperature. According experimental data, sign mixture under study changes at temperature 285.4 K. work consider range such that inside simulated region. Other transport coefficients factors considered as constant. were cases Earth reduced gravity. A comparison is made case value, which negative average
