The Magnetic Induction Equation
using the KS Model
We use the KS model to simulate the turbulent flow which twists and distorts
our magnetic field according to the magnetic induction
We would like to examine the behaviour of the magnetic field in different
environments and to this end, we can vary many parameters.
An obvious choice of parameter to vary is eta, the magnetic diffusivity. With
everything else held fixed, this will change the magnetic Reynolds number (and hence Pm).
Alternatively, we can alter the length scales in the KS model (i.e. change the
Reynolds number of the flow), vary the speed at which the eddies turn over, or even change the slope of the energy spectrum
of the KS-generated velocity field. Typical results for each of the cases are
available by clicking the links below.
