THE DISSOLVING IMPURITIES INFLUENCE THEORETICAL ESTIMATION IN LIQUID GASES ON THE INTENSITY OF MIXING AT THEIR STORAGE IN CRYOGENIC TANKS
Theoretical analysis of the hydrothermal situation in a cryogenic tank during the storage of liquefied gases under the conditions of a soluble sediment of highboiling impurities on a wetted surface is considered taking into account the heat flow through the walls due to the imperfection of thermal insulation. On the basis of the physical linearization of the Oberbeck-Boussinesq equations, a nonconjugated mathematical model is formulated with respect to the fields of velocities, temperatures and concentrations.An analytical solution for imitation geometry (square rug) is obtained. The results of computational experiments confirmed the phenomenon of mutual suppression of thermal and concentration natural convection.
