摘要/Abstract

摘要： 针对激光腔靶内流场的复杂性给出了一种欧氏与拉氏格式相结合、一维与二维计算相结合的方法,我们把它称为EL-1D2D方法。这种方法在跟踪界面活动网格方法的基础上,建立了设置欧拉线以及在欧拉线的一侧进行网格自动合并的计算技术,从而适应了腔体内比较复杂的流动。数值试验的结果表明,用这种方法计算腔靶流场的运动可以得到合理的物理图象。

Abstract: In view of the complexities of laser cavity target flow, a numerical technique is presented that couples an Eulerian approximation with a Lagrangian approximation,onedimensional calculation with two dimensional calculation. We call it EL-1D2D method. On the basis of trace interface moving grid method, some particular technique is established mainly by setting an Eulerian line and by merging the zone adaptively beside the Eulerian line. Numerical results show that this method can calculated fairly complicated flow in the cavity and get reasonable physical image.

Key words: laser cavity target flow, EL-1D2D method, Eulerian line
