In this paper we report on the outline of a Large Eddy Simulation subgrid model for liquid/gas phase interface dynamics. A key feature of the proposed model is to take the subgrid phase interface dynamics fully into account by employing a dual-scale approach. Instead of modeling the LES subgrid phase interface geometry, we fully resolve it on an auxillary grid using the Refined Level Set Grid a...

Rotary atomizers are mainly used in agricultural manned aircrafts. Atomization characteristics at high speeds have been studied, but methods to measure the atomization efficiency not elucidated. The of rotary under high-speed airflow was investigated using an IEA-I wind tunnel experimental installation, AU5000 atomizer, and a laser diffraction particle size analyzer. Accordingly, model equation...

This review summarizes and discusses the analytical methods and techniques described in the literature for hydride generation as a mode of slurry sample introduction into atomization cells. A brief comparison of detection limits for analytical atomic absorption methods and practical applications to analytical samples that utilize slurry hydride generation is discussed. The current state-of-the-...

In this paper we report on a numerical method to include Marangoni forces into a finitevolume solver for multi-phase flows. Our work is motivated by the question of whether thermal fluctuations typically found in combustion applications can impact the atomization of fuel drops due to variations in surface tension. To verify and validate our proposed method, we compare our results to theoretical...
