| Abstract: | The interaction of phase-mixed Alfvén waves with an inhomogeneous cold plasma
density, transverse to magnetic field, may excite the non-linear fast
magnetosonic waves. Phase mixing of the Alfvén waves produce strong transversal gradients in the amplitude. The
strong transversal gradients in amplitude of the Alfvén wave leads to the
dissipation of Alfvén wave energy. The
dissipation of the phase-mixed Alfvén wave in inhomogeneous cold plasma is
conversion to the non-linear excitation of the fast magnetosonic waves. The
linear coupling of the phase-mixed Alfvén waves and fast magnetosonic waves may
be a possible mechanism of solar coronal heating. Here, this heating mechanism
has been considered with viscosity, resistivity and thermal conductivity in an
inhomogeneous plasma medium. |
