The development of two-dimensional and three-dimensional simulations of solar convection has lead to a picture of convection quite unlike the usually assumed Kolmogorov spectrum turbulent flow. We investigate the impact of this changed structure on the dissipation properties of the convection zone, parameterized by an effective viscosity coefficient. We use an expansion treatment developed by Goodman & Oh, applied to a numerical model of solar convection, to calculate effective viscosity as a… Expand

Direct Calculation of the Turbulent Dissipation Efficiency in Anelastic Convection
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 valid for some casesExpand
Dissipation Efficiency in Turbulent Convective Zones in Low Mass Stars

The impact of rotation on turbulent tidal friction in stellar and planetary convective regions
Context. Turbulent friction in convective regions in stars and planets is one of the key physical mechanisms that drive the dissipation of the kinetic energy of tidal flows in their interiors and theExpand
On the frequency-dependent effective viscosity of laminar and turbulent flows
The efficiency of tidal dissipation in convective zones of stars and giant planets depends, in part, on the response of a three-dimensional fluid flow to the periodic deformation due to theExpand
