摘要：

New numerical results on thermal gravity-driven convection in a layer filled with near-critical He-3 and heated from below are presented. Corrections of conditions for convection onset are discussed. The heat transfer calibrations near the critical point are tested using experimental data. Stratification effects are analysed. As found, space environment that suppresses the strong density gradients near the critical point may provoke the enhancement of convection compared to the terrestrial conditions.
