Memoryless drop breakup in turbulence Science Advances

WebIn this study, numerical breakup experiments are used to study turbulent fragmentation of viscous drops, under conditions similar to emulsification devices such as high-pressure homogenizers and rotor-stator mixers. The drop diameter was kept larger than the Kolmogorov length scale (i.e., turbulent inertial breakup). Web18 jun. 2010 · In the simulations LES e.g. produces an expected turbulent dispersion pattern that depends on droplet diameter ( d) without a droplet dispersion model in contrast to RANS. A new compact droplet breakup model is formulated and tested for droplets that break with a natural resonance time rate according to the Poisson process.
