将Rogava最近提出的非模态自加热机制应用于沿着磁力线有非均匀等离子体流的冕洞介质。假设粘性力是各向异性的。的非模态级联过程的效率进行检查，为不同的环境参数和不同的波参数。它的结论是，所提出的机制可以作为一种替代机制，用于解释显着的热量产生在较低的电晕，即使只有层流值的粘度系数被考虑在内。
The nonmodal self-heating mechanism recently proposed by Rogava is applied to the medium of solar coronal holes with an inhomogeneous plasma flow along the magnetic field lines. The viscosity force is assumed to be anisotropic. The efficiency of the nonmodal cascade process is examined for different sets of environmental parameters and for different wave parameters. It is concluded that the proposed mechanism can serve as an alternative mechanism for explaining the significant heat production in the lower corona, even when only laminar values of the viscosity coefficients are taken into account.
