Interface reconstruction method for multiphase flows in under-resolved regions

Résumé

This paper presents an interface reconstruction method called moment of uid (MOF) method for two-phase ows using statistical moments of liquid volume fraction. In each ow solver grid cell, the liquid volume fraction and liquid center of mass are used for computing the interface unit normal. The transport of the liquid volume fraction and center of mass is performed by a directionally split advection scheme. This method is validated, results are compared with those from coupled level set volume of uid (CLSVOF) method for 2D and 3D test cases, and is found to be at least secondorder accurate in spatial resolution. Furthermore, MOF method is shown to outperform CLSVOF method in terms of interface reconstruction for thin and underresolved liquid ligaments and laments thereby conserving mass in the domain.
