| Abstract: |
We construct a 3D magnetic model for the dissipation and propagation
of Alfvén waves in a coronal loop. The waves are
assumed to be generated by foot-point motions inside the kilogauss
magnetic flux elements at the two ends of the loop. Counter
propagating waves are subject to non-linear interactions that lead to
turbulent decay of the waves and heating of the chromospheric and
coronal plasma. We find that hot coronal loops typically found in
active region and the underlying chromosphere can be explained by Alfvén wave turbulence. |
