强磁场环境下磁流体数值模拟系统开发与应用

基于强磁场环境下聚变堆包层中液态金属流体的基本物理过程，采用三阶龙格库塔四步投影法求解N_S方程，相容守恒格式计算电流和电势，建立符合该现象的磁流体动力学方程组，设计开发数值模拟系统。由于该文构造的离散模型具有很好的守恒特性和精确度，数值模拟结果表明该系统对研究磁流体MHD效应，揭示磁流体流动压降、流速分布，对提高磁流体动力学系统设计效率及工程应用具有很好的参考价值。

Design and Application of Magnetal Fluid in Strong Magnetic Field ＇ s Numerical System

This paper is based on the basic physical process of the liquid metal flow in strong magnetic field fusion reator.Three stage Runge-Kutta method is used to slove the Navier-Stokes equation,and a conservetive and accurate scheme are introduced to compute current and electrical potential,established magenetic fluid dynamic equations and designed the numerical simulation system.For the good accuration and conservative character of the discreate scheme,the result of the simulation(include pressure drop,velocity distribution etc.) indicate that this systerm is very useful to improve the magnetohydrodynamics’ system design efficiency and project application.
