Abstract

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.
