研究了垂直Hele-Shaw槽中平行流动的两粘性流体分离界面上非线性行波的发展。其中一种流体是磁流体，在电池的平面上施加一个均匀的磁场，使其与最初未受干扰的界面成一定角度。我们采用了一种模式耦合理论，该理论预测了通过纯磁性手段控制波速度的可能性。研究了倾斜磁场对波形分布的影响，建立了稳定的行波结构。
We study the development of nonlinear traveling waves on the interface separating two viscous fluids flowing in parallel in a vertical Hele-Shaw cell. One of the fluids is a ferrofluid and a uniform magnetic field is applied in the plane of the cell, making an angle with the initially undisturbed interface. We employ a mode-coupling theory that predicts the possibility of controlling the speed of the waves by purely magnetic means. The influence of the tilted magnetic field on the waves shape profile and the establishment of stationary traveling wave structures are investigated.
