Large Eddy Simulation of an evaporating acetone spray

The LES-Lagrangian particle methodology is applied to the study of vaporizing particle laden flows. A probabilistic description of the liquid phase is adopted and stochastic models for the filtered Lagrangian rates of change of droplet mass and temperature of the spray are presented. The method is applied to an acetone spray which issues into an air co-flow to form an evaporating droplet laden jet. Comparisons of the LES results with measurements demonstrate that the essential features of the flow are reproduced to a good accuracy.
