Turbulence in proto-planetary accretion disks

Numerical Simulations of gas dynamics on high performance computers.

February 08, 2022

If you are interested in working with numerical tools on turbulence in disks around young stars, this is the right project for you.

Disks around young stars are the birthplace of planets. The dust and ice particles are suspended in the turbulent gas, which controls their transport and collisions, diffusion and concentration, growth and fragmentation. In this project we study various causes for the turbulence, from hydro dynamical as well as magneto hydro dynamical perspective.

We perform three-dimensional numerical simulations on high performance computers. If you know c or python and like to perform and analyze simulations, this project is right for you.

 

The radial temperature gradient in a disk drives a thermal wind, i.e. vertical shear. This is unstable in the presence of thermal relaxation, i.e. heating and cooling.
