Turbulent eddy viscosity and large-scale convection in the Sun

It is suggested here that the laminar character of the large-scale deep convective flows appearing in numerical simulations of the convective envelope of the Sun arises from the effect of turbulent eddy viscosity. Previously, M. Schwarzschild suggested the same idea to explain the observed surface g...

Zusammenfassung:It is suggested here that the laminar character of the large-scale deep convective flows appearing in numerical simulations of the convective envelope of the Sun arises from the effect of turbulent eddy viscosity. Previously, M. Schwarzschild suggested the same idea to explain the observed surface granulation in the Sun.
