Replication Data for \"Beyond the Oberbeck-Boussinesq and long wavelength approximation\"

Dataset to the study on arbitrary wavelength polarization and non-Oberbeck-Boussinesq effects on interchange blob propagation that is published under the title \"Beyond the Oberbeck-Boussinesq and long wavelength approximation\" M. Held and M. Wiesenberger Abstract: We present the first simulations of a reduced magnetized plasma model that incorporates both arbitrary wavelength polarization and non-Oberbeck-Boussinesq effects. Significant influence of these two effects on the density, electric potential and ExB vorticity and non-linear dynamics of interchange blobs are reported. Arbitrary wavelength polarization implicates so-called gyro-amplification that compared to a long wavelength approximation leads to highly amplified small-scale ExB vorticity fluctuations. These strongly increase the coherence and lifetime of blobs and alter the motion of the blobs through a faster blob-disintegration. Non-Oberbeck-Boussinesq effects incorporate plasma inertia, which substantially decreases the growth rate and linear acceleration of high amplitude blobs, while the maximum blob velocity is not affected. Finally, we generalize and numerically verify unified scaling laws for blob velocity, acceleration and growth rate that include both ion temperature and arbitrary blob amplitude dependence.

本数据集用于研究任意波长极化及非奥伯贝克-布辛涅斯克效应（non-Oberbeck-Boussinesq effects）对交换 blob（interchange blob）传播的影响，相关研究成果发表于题为《超越奥伯贝克-布辛涅斯克与长波长近似》（Beyond the Oberbeck-Boussinesq and long wavelength approximation）的论文中，作者为M. Held与M. Wiesenberger。

摘要：我们首次开展了纳入任意波长极化及非奥伯贝克-布辛涅斯克效应的简化磁化等离子体模型模拟。研究报告了这两种效应对交换 blob 的密度、电势、ExB 涡度（ExB vorticity）及非线性动力学的显著影响。任意波长极化涉及所谓的陀螺放大（gyro-amplification），与长波长近似相比，其可导致小尺度ExB涡度波动被高度放大。这会显著增强 blob 的相干性与寿命，并通过加快 blob 解体改变其运动特性。非奥伯贝克-布辛涅斯克效应包含等离子体惯性（plasma inertia），后者大幅降低高振幅 blob 的增长率与线性加速度，但不影响其最大速度。最后，我们推导出并通过数值验证了统一标度律（scaling laws），该标度律涵盖离子温度及任意 blob 振幅依赖性。
