Abstract

A theoretical investigation associated with obliquely propagating ion-acoustic shock waves (IASHWs) in a three-component magnetized plasma having inertialess non-extensive electrons, inertial warm positive, and negative ions has been performed. A Burgers equation is derived by employing the reductive perturbation method. The plasma model supports both positive and negative shock structures. It is found that the positive and negative shock wave potentials increase with the oblique angle (\(\delta \)) which arises due to the external magnetic field. It is also observed that the magnitude of the amplitude of positive and negative shock waves is not affected by the variation of the ion kinematic viscosity but the steepness of the positive and negative shock waves decreases with ion kinematic viscosity. The implications of our findings in space and laboratory plasmas are briefly discussed.

磁化对离子等离子体中的离子声冲击波

摘要

已经进行了与在具有无惯性非扩展电子，惯性热正离子和负离子的三组分磁化等离子体中倾斜传播的离子声冲击波（IASHWs）相关的理论研究。通过采用归纳摄动法来推导Burgers方程。等离子体模型支持正激结构和负激结构。发现正和负冲击波电势随斜角（\（\ delta \）增大）是由于外部磁场而产生的。还可以观察到，正向和负向冲击波幅度的大小不受离子运动粘度变化的影响，但是正向和负向冲击波的陡度随离子运动粘度而减小。简要讨论了我们在太空和实验室等离子体中发现的意义。
