Free convection. Accounting for certain physical features when simulation software using for modeling convection flows

In the work of the highlighted features of the dynamics of convective flows induced by gravity and temperature gradients, the mathematical model describing their behavior, and the condition of mechanical equilibrium liquid when heated, the conditions of formation of stable and unstable convective flows. Given the similarity laws for free convection and heat transfer. These results enable to significantly increase the efficiency of numerical modeling with the aim of producing recommendations to the synthesis need to create devices sustainable convection currents by variation geometry, distribution gradients control of the temperature field and the parameters of the working fluid.
