An Endoreversible Thermodynamic Model Applied to the Convective Zone of the Sun
Figure 2
Schematic diagram of the energy fluxes present in the first internal convective cell. at 0.714 is taken as the temperature of the first isothermal layer, is taken as the cold reservoir temperature, and is taken as the upper shell temperature of the first convective cell. Short arrows indicate that emitted radiation is rapidly absorbed by opaque gases.
