电离驱动漂移波湍流理论是在准局域模型的背景下提出的。线性分析表明，电离效应可以破坏碰撞漂移波的稳定性，也可能引起平行剪切流的不稳定性。非线性分析表明，能量从大尺度向小尺度转移，并转化为离子动能。结果表明，模式耦合效应占主导地位。预测了大的波动水平，超过混合长度的预期。电离源驱动一个纯粹向内的粒子流，这可以解释响应于气体抽吸而发生的粒子的异常快速吸收。
The theory of ionization‐driven drift wave turbulence is presented in the context of a quasilocal model. Linear analysis reveals that ionization effects can destabilize collisional drift waves and can possibly induce parallel shear flow instabilities, as well. Nonlinear analysis indicates that energy is transferred from large to small stable scales and converted to ion kinetic energy. Results indicate mode coupling effects are dominant. Large fluctuation levels, in excess of mixing length expectations, are predicted. The ionization source drives a purely inward particle flux, which can explain the anomalously rapid uptake of particles that occurs in response to gas puffing.
