A consistent momentum transport in CLSVOF method: validation on jet atomization

Abstract

Many atomization processes are characterized by large density ratios coupled with large shear. Numerical simulations are known for becoming unstable in these physical conditions. We developed a new mass and momentum consistent algorithm for CLSVOF method. Based on Rudman's work, the originality of our approach is to avoid using a sub-grid by splitting flux calculation between neighboring cells. The method is validated by comparing simulations with theoretical results and experimental air assisted atomization of a coaxial jet.
