摘    要:研究了非均匀磁场中多质量射流的运动轨迹,推导出质量色散强度表达式。考虑到不同入射方式及羽流角度的情况下,应用MATLAB模拟射流的运动轨迹,计算出质量色散强度,并同均匀磁场中的质量色散强度大小相比较,以确定该种磁场中射流质量分离的效果。模拟结果表明:非均匀磁场中多质量射流的质量色散强度大于均匀磁场的情况,可实现等离子体射流的高效质量分离。

关 键 词:多质量射流    非均匀磁场    质量色散强度    运动轨迹

Abstract:Mass dispersion research of multi-mass plasma jet has important position in fields like separator or spectrometer. This paper studies the movement trajectory of multi-mass jet flow in inhomogeneous magnetic field and deduces an expression of mass dispersion. Considering the different incident angle and plume, we apply MATLAB to simulate motion trajectory of jet flow, calculate mass dispersion, and compare the result with mass dispersion in homogeneous magnetic field to confirm the effect of jet flow mass separation in this magnetic field. The simulation results show that the mass dispersion of multi-mass jet in inhomogeneous magnetic field is greater than that in homogeneous magnetic field, and that the mass separation of plasma jet can be efficiently realized.
Keywords:multi-mass jet flow  inhomogeneous magnetic field  mass dispersion intensity  motion trajectory
