Model comparison for angle droplet fragmentation under varying accelerations

Different models for single droplet fragmentation have been assessed for different initial accelerations in the bag and sheet-thinning regimes. The predictions have been compared to high-speed-video sequences where a single droplet is injected in a cross-flow of air. It is concluded that the modeling of the temporal evolution of the breakup...

An extension of dynamic droplet deformation models to secondary atomization

A detailed model for secondary atomization of liquid droplets by aerodynamic forces is presented. As an empirical extension of dynamic droplet deformation models, it accounts for temporal variations of the relative velocity between droplet and gas phase during the deformation and breakup process and describes the characteristic features of...
