已经进行了实验和数值模拟，以研究稳定磁场存在下汞层中二维湍流的特性。通过观察自由表面并使用位于流体层底部的电位探针，记录涡流的可视化和速度的定量测量。同时，使用层流纳维-斯托克斯方程和模拟哈特曼摩擦的源项进行了一些二维数值模拟。
An experiment and numerical simulations have been carried out to investigate the properties of 2D turbulence in a mercury layer in the presence of a steady magnetic field. Visualisation of the vortices and quantitative measurements of the velocity were recorded, via the observation of the free surface and using potential probes located at the bottom of the fluid layer. In parallel, some 2D numerical simulations were issued, using laminar Navier-Stokes equations with a source term modelling the Hartmann friction.
