该文研究了均匀轴向磁场对含脉动速度射流参数稳定性的影响.通过建立雾化气体和金属射流的双流体模型,推导出描述射流界面扰动量的参数振动方程,得到了均匀磁场作用下流动的稳定与不稳定区域,并且通过数值计算获得了破碎粒径的变化与其中所含参量的关系.

This paper studied the effects of uniform magnetic field on the parametric instability of jet with pulsating basic velocity. By constructing a twofluid model of gas and liquid metal, a system of parametric vibration equations describing the disturbance of interface is derived, and the stable and unstable regions under the effects of the uniform magnetic field are obtained. Numerical results show the relation between the diameter of breakup drop and different parameters.
