A novel way of implementing surface tension effects in sharp-interface compressible flow models is proposed, aiming to address problems where liquid compressibility and capillarity are both important. The method is built on the principles of the grid-aligned formulation for ghost fluid techniques. In this approach, the Riemann problems at the interface are formulated along the grid rather than in a normal-to-the-interface direction; the method is thus simpler. The performance of the method is thoroughly examined following implementation in a well-established front tracking framework.

具有毛细作用的可压缩多组分流的简单鬼流方法

提出了一种在锐口可压缩流动模型中实现表面张力效应的新颖方法，旨在解决液体可压缩性和毛细作用均很重要的问题。该方法建立在用于重影流体技术的网格对齐公式的原理上。在这种方法中，界面处的黎曼问题是沿着网格而不是沿着法线到界面的方向表达的；该方法因此更简单。在完善的前端跟踪框架中实施后，将彻底检查该方法的性能。
