| Abstract: | Natural-convection flows in continua are studied at the parameter values beyond the critical point of the liquid-gas phase transition. The theory of similarity of supercritical convective flows is generalized by taking account for the dependence of the thermodynamic properties of a medium on the temperature and the density. In the case of an arbitrary two-parameter medium calibration relations, which serve for determining the similarity criteria of convection, are derived. In the fluid with the Van der Waals equation of state the calibration relations are reduced to the form of functions of the dimensionless temperature and density. |
