We verified the validity of the criterion proposed by Hinze (1955) for droplet breakup and we measured the full probability distribution function (pdf) of droplets radii at different Reynolds numbers and for different volume fraction. By means of a Lagrangian tracking we could follow individual droplets along their trajectories, define a local Weber number based on the velocity gradients and study its cross-correlation with droplet deformation.", "revisions": [ { "version": "v1", "updated": "2011-12-28T01:32:56.000Z" } ], "analyses": { "subjects": [ "47.55.df", "47.27.eb", "47.27.Gs", "02.50.Cw", "47.11.Qr" ], "keywords": [ "droplet size distribution", "homogeneous isotropic turbulence", "droplet breakup", "full probability distribution function", "multicomponent lattice boltzmann method" ], "tags": [ "journal article" ], "publication": { "doi": "10.1063/1.4719144", "journal": "Physics of Fluids", "year": 2012, "month": "Jun", "volume": 24, "number": 6, "pages": 5101 }, "note": { "typesetting": "TeX", "pages": 10, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2012PhFl...24f5101P" } } }
