In this research, the height, curvature and velocity of the bubble tip in Rayleigh–Taylor instability at arbitrary Atwood number with horizontal magnetic field are investigated. To support the earlier simulation and experimental results, the vorticity generation inside the bubble is introduced. It is found that, in early nonlinear stage, the temporal evolution of the bubble tip parameters depends essentially on the strength and initial perturbation of the magnetic field, although the asymptotic nature coincides with the nonmagnetic case. The model proposed here agrees with the previous linear, nonlinear and simulation observations.

水平磁场的非线性瑞利-泰勒不稳定性

在这项研究中，研究了在水平磁场作用下任意阿特伍德数下瑞利-泰勒不稳定性中气泡尖端的高度，曲率和速度。为了支持早期的仿真和实验结果，引入了气泡内部的涡度生成。已经发现，在非线性的早期阶段，尽管渐近性质​​与非磁性情况相吻合，但气泡尖端参数的时间演变基本上取决于磁场的强度和初始扰动。这里提出的模型与以前的线性，非线性和模拟观察结果一致。
