Dahlburg coronal heating
WebAug 6, 1999 · The dissipation coefficient and the spatial scale at which the dissipation occurs help determine the coronal heating mechanism. Heating of coronal loops may occur by trapped Alfvén waves (), or by reconnection of entangled magnetic field ().The theoretical classical value of the dissipation coefficient is determined by viscosity and … WebDec 4, 2024 · Abstract.
