Abstract
ABSTRACT In this paper, turbulent properties and correlations of Helium convective shells (due to partial ionization of Helium) of 30 $\, \mathrm{M}_{\odot }$ star are researched. As evolution proceeds, the turbulence in Helium convective shells becomes more and more intense. Choosing the stellar models of which effective temperature is 10 000 Kelvin, it is found that the turbulent kinetic energy will increase in the Helium II (primary Helium ionization) zone but decrease in the Helium III (Helium secondary ionization) zone and the ratio of convective heat flux to the total heat flux will increase in the He ii convective zone and decrease in the He iii convective zone as the turbulent diffusion parameters’ values increase. This represents that the turbulent kinetic energy possibly transport outward as the turbulent diffusive parameters’ values increase.
