Solar Washing Machine Movies of Model Evolution (2)
In this post we describe the configurations used for the solar washing machine simulations. We consider
Matlab routines used to generate sections
The following matlab routine was used to generate videos illustrating the variation of the vertical component of the plasma flow velocity in the model
- plotsecs_array.m used to generate Velocity slice with velocity quiver. (rhosecs_vquiv)
This is git commit https://github.com/mikeg64/smaug_wash/commit/21b55d398b43195b3ffec5f7974bdbccc7d97108 Colours show plasma velocity magnitude at 3rd layer of the model i.e. taken perpendicular to the x-axis, contours show the perturbed magnetic field magnitude quiver arrows indicate the plasma velocity.
Method
The results presented here were generated from the configurations uni1, uni5 and uni6 described at: Solar Washing Machine Single Frequency Driver Rerun 2.
For this series of runs the driver amplitude was varied.
- uni1 aa=10m/s
- uni5 aa=5m/s
- uni6 aa=20m/s
We used the matlab routine plotsecs_array.m to generate the plots for all timesteps.
The results display clear evidence of MHD waves.
Results
uni1
3d view of vertical component of velocity
uni5
3d view of vertical component of velocity
2d view showing mutually perpendicular slices and the B field magnitude, lower figure shows a horizontal slice at the bae of the model
uni6
3d view of vertical component of velocity
2d view showing mutually perpendicular slices and the B field magnitude, lower figure shows a horizontal slice at the bae of the model
The magnetic field movies illustrate kink motions of the magnetic flux tube, along with a propagating wavefront. This was revealed after some data exploration using paraview. We illustrate some results generated using paraview and describe the techniques used.
