Abstract
In a next generation dynamo experiment currently under development at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) a fluid flow of liquid sodium, solely driven by precession, will be considered as a possible source for magnetic field generation. We will present results from non-linear hydrodynamic simulations with moderate precessional forcing dedicated to the planned experiment.
Our results have been used for flow models in kinematic dynamo simulations in order to determine whether a precession driven flow will be capable to drive a dynamo at experimental conditions and to limit the parameter space within which the occurrence of dynamo action is most promising.
Keywords: dynamo; precession; DRESDYN
