 note = {The convection phenomena in a layered liquid system have been analyzed by a few papers^ [1-4)]. At least two motivations for the activity in this area can be pointed out: 1) To intensify convective mixing in liquids (chemical engineering). 2) To reduce convective mixing in liquids (space technology). Covering main liquid by another one having definite properties, we can reduce or enlarge convective motion in the lower liquid. Hydrodynamical and thermal interaction changes the characteristics of convective motion in both layers. The change of physical parameters in one of the layers permits to influence the hydrodynamics and heat transfer in the other layer. In general, the structure of convective flow in the layers depends on the volumetric buoyancy force and the thermocapillary stress at the free surface and interface. In the case of reduced gravity the input of various components into the balance of forces acting in a liquid changes drastically. The thermocapillary force begins to play an important, and in many cases, decisive role due to the existence of surface tension dependence on temperature. To investigate the influence of different factors such as gravity, viscosity, thermoconductivity and thermocapillarity upon main characteristics of velocity and temperature fields in a two-layered system, a multiparametric numerical study of a two-dimensional model on thermogravitational and thermocapillary convection is carried out.},
