Direct Calculation of the Turbulent Dissipation Efficiency in Anelastic Convection
Kaloyan Penev, Joseph Barranco, Dimitar Sasselov
The current understanding of the turbulent dissipation in stellar convective zones is based on the assumption that the turbulence follows Kolmogorov scaling. This assumption is val…
First Results From New 3D Spectral Simulations Of Anelastic Turbulent Convection
Kaloyan Penev, Joseph Barranco, Dimitar Sasselov
We have adapted the anelastic spectral code of Barranco & Marcus (2006) to simulate a turbulent convective layer with the intention of studying the effectiveness of turbulent eddie…
On Dissipation inside Turbulent Convection Zones from 3D Simulations of Solar Convection
Kaloyan Penev, Dimitar Sasselov, Frank Robinson +1
The development of 2D and 3D simulations of solar convection has lead to a picture of convection quite unlike the usually assumed Kolmogorov spectrum turbulent flow. We investigate…
