Abstract

The next generation dynamo experiment currently under development at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) will consist of a precessing cylindrical container lled with liquid sodium. We perform numerical simulations of kinematic dynamo action applying a velocity eld that is obtained from hydrodynamic models of a precession driven flow. So far, the resulting magnetic eld growth rates remain below the dynamo threshold for magnetic Reynolds numbers up to Rm = 2000.
