Solar granulation - The influence of viscosity laws on theoretical models
Abstract
Numerical simulations of solar granulation are presented. Emphasis is given to the influence of various viscosity laws on predictions of the velocity field, the degree of overshooting into upper stable layers, and the degree of sensitivity to overall changes in viscosity. The depth dependence of the Prandtl number in a solar granulation model having a constant dynamic viscosity of 0.005, is illustrated in graphic form.
