Dependence of the Radiative-Convective Equilibrium Structure of the Lower Atmosphere of Venus on the Thermodynamic Model

Dependence of the radiative-convective equilibrium structure lower atmosphere Venus on specification atmospheric thermodynamic model is investigated. A series models including ideal gases, van der Waals and real gases are introduced by use Helmholtz energy given EOS-CG mixture (EOS-CG: Equation State for Combustion Gases Gas-like Mixtures). It demonstrated that profile gas differs significantly from with temperature-dependent specific heat an increase about 7 K in surface temperature. This difference caused fact adiabatic lapse rate evaluated larger than gas, since non-ideality increases thermal expansion coefficient, which overwhelms density heat. confirmed that, order to obtain better calculations circulations Venus, a constant should be abandoned. The may not enough. promising method but such its mimics gas.
