A critical comparison of smooth and sharp interface methods for phase transition

Autor: M.W. Baltussen, A. Panda, A.H. Rajkotwala, J.A.M. Kuipers, Eajf Frank Peters, Johannes G.M. Kuerten, C.W.M. van der Geld

Publikováno v: International Journal of Multiphase Flow, 120:103093. Elsevier

In this study, the Local Front Reconstruction Method (LFRM) is extended to allow for the direct numerical simulation of flows with phase transition. The LFRM is a hybrid front tracking method without connectivity, which can easily handle complex topo

Publikováno v: Physics of Fluids, 30(2):022102. American Institute of Physics

The physics of droplet collisions involves a wide range of length scales. This poses a challenge to accurately simulate such flows with standard fixed grid methods due to their inability to resolve all relevant scales with an affordable number of com
