We consider the Alfvén wave self-interaction in a plasma with thermal misbalance. To describe this process, a system of truncated equations is obtained that allows using a relatively simple algorithm for its numerical solution. The obtained truncated system describes the self-interaction of Alfvén waves under various conditions of thermal misbalance and thermal instabilities. The results obtained by numerically solving the truncated system are consistent with the results obtained by solving the full system of one-dimensional MHD equations.

等离子体中具有热失衡的阿尔文波自相互作用

我们考虑具有热失衡的等离子体中的阿尔文波自相互作用。为了描述这个过程，得到了一个截断方程组，它允许使用相对简单的算法来求解。获得的截断系统描述了阿尔文波在各种热失衡和热不稳定性条件下的自相互作用。数值求解截断系统得到的结果与求解一维MHD方程全系统得到的结果一致。
