Numerical study of interface reconstruction method in under-resolved regions of the flow for liquid jet primary breakup

Abstract : Liquid/gas interface reconstruction continues to be a challenge in the numerical study of liquid fuel atomization. This paper focuses on one such reconstruction method called moment of fluid (MOF) method intended specifically for interface reconstruction in under-resolved flow regions. MOF method gives twofold advantage over volume of fluid (VOF), level set (LS), and coupled level set volume of fluid (CLSVOF), such as: first, MOF preserves the shape and orientation of interfaces that are commonly encountered in under-resolved regions of the flow, and second, it exhibits second-order accuracy in spatial resolution for multiple interface topologies. For various test cases considered in this paper, MOF has consistently proved to be more accurate than and at least as accurate as CLSVOF method.
