Current Coefficient Law in Simulation of Magnetically Driven Solid Liner Experiment
The magnetically driven solid liner experiments on the FP-2 device were simulated and analyzed based on the incompressible theoretical model.The simulation results show that the boundary magnetic induction strength formula for the magnetically driven solid liner of the reflux hood structure contains a liner current coefficient of less than 1,regardless of whether it is a two-dimensional magnetohydrodynamic(MHD)theoretical model or other incompressibility theoretical models.The current coefficient law of the magnetically driven solid liner experiment on the FP-2 was studied by simulating the magnetically driven solid liner experiment with different thickness and radii.The current coefficient of magnetically driven solid liner experiment is not only related to the liner's inner radius,but also to the liner's thickness.The larger the inner radius of the liner,the smaller the current coefficient,and the larger the thickness of the liner,the smaller the current coefficient.Exploring the current coefficient law in magnetically driven solid liner experiment with reflux hood structure can make the MHD code develop from post-simulation to accurate prediction.And the MHD theoretical model can be employed to design correctly and guide the related experiments of magnetically driven solid liner with a reflux hood structure.
