Numerical simulation of evaporating charged sprays in spray chilling

In this research we investigate whether charged sprays offer any improvements over conventional spray in the spray-chilling of meat. A Eulerian-Lagrangian CFD modelling approach is developed and validated with results from automotive spray painting. The model is then extended to include evaporation and the transport of evaporation products. The simulation results show doubling of the spray transfer efficiency as well as a notable increase in the rate of cooling when electric charge is applied to the spray. Furthermore, the presented modelling approach yields consistent results at low computational costs, making it suitable for use in future design optimisation studies.
