Turbulent convection in stellar interiors : a numerical approach using time-implicit simulations

Maxime Viallet (U. of Exeter)
Jeudi 26 Avril - 11 h 00
Salle Manuel Forestini - IPAG

Convection is a key process in stellar interiors. It is characterized by large Reynolds numbers, implying a highly turbulent regime. I will show how multidimensional hydrodynamical simulations allow us to get a physical insight of this complex phenonemon. The numerical results are obtained with a fully implicit method, and in the talk I will present the general framework and discuss the advantages of implicit methods in tackling stellar hydrodynamical problems.
