Local effects of the weak thermogravitational convective flows

The features of the natural low intensity thermo-gravitational convection occurring in microacceleration condition have been investigated numerically. The effect of thermal boundary conditions on the local characteristics of temperature field has also been studied. It was shown that the value of maximum temperature stratification depends monotonically on the intensity of heat transfer at the system boundaries. The correction algorithm has been proposed for the vorticity boundary conditions on the solid impermeable walls.
