Title: Application of Detached Eddy Simulation to Lagrangian Spray Simulations
Abstract: In this study, the influence of turbulence models on the prediction of turbulent structures is investigated by example of a hollow-cone spray. The focus is put on the general character of the turbulence models, i.e. the production and dissipation of turbulence and the dispersion of the disperse phase. The models in focus include five RANS and LES models, and a Detached Eddy Simulation, which shows LES behavior in the free flow, and falls back to a RANS simulation in regions of small turbulent length scales. Results indicate that Detached Eddy Simulations are less mesh sensitive than true LES, while resolving turbulent features in an LES manner.
