Goedbloed}, title = {Nonlinear mhd simulations of wave dissipation in flux tubes}, abstract = {The phase mixing and resonant dissipation of Alfven waves is studied in both the 'closed' magnetic loops and the 'open' coronal holes observed in the hot solar corona. The resulting energy transfer from large to small length scales contributes to the heating of these magnetic structures. The nonlinear simulations show that the periodically varying shear flows that occur in the resonant layers are unstable. In coronal holes, the phase mixing of running Alfven waves is speeded up by the 'flaring out' of the magnetic field lines in the lower chromosphere.}, year = {1997}, journal = {Solar Physics}, volume = {172}, number = {1-2}, pages = {45-52}, month = {May}, isbn = {0038-0938}, doi = {10.1023/a:1004924017304}, language = {eng}, }
