Fluid film break-up modeling using adaptive mesh refinement models

Abstract

Numerical modelling of fluid film break-up is carried out using adaptive mesh models. The results obtained are compared with experimental data. It is shown that using local adaptation with hanging nodes allows reaching a sufficient accuracy of fluid film boundaries estimation and definition of droplet dimensions resulted from its atomization. It is noticed that these are not only a turbulence model and adaptation sequence selection that substantially affect the computation results but also a type of initial mesh model.
