Memoryless drop breakup in turbulence
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). Web19 dec. 2024 · The disintegration of drops and bubbles by chaotic swirls in turbulence is common in everyday life: When taking a shower or using a spray bottle to disperse a …
Memoryless drop breakup in turbulence
Did you know?
WebDrop breakup in fluid flows is investigated here as an exchange between the fluid's kinetic energy and the drop's surface energy. WebA theoretical model for the prediction of drop and bubble (fluid-particle) breakup rates in turbulent dispersions was developed. The model is based on the theories of isotropic …
Web1 aug. 2009 · In this work, we show that drop breakup in homogeneous isotropic turbulence obeys a memoryless process whose rate depends only on the Weber … WebThe breakup of drops and bubbles in turbulent fluids is a key mechanism in many environmental and engineering processes. Even in the well-studied dilute case, …
Web1 dec. 2015 · The largest uncertainty is associated with the determination of the breakup time because the bubbles take continuously altering deformed shapes already from the point of injection into the tank. The present experimental data do not support the standard model assumption regarding the number of daughter particles.
WebThese findings shed new light on drop deformation and breakup in turbulent flows, and opens the possibility for the improvement and simplification of breakup models. Abstract …
Web16 dec. 2024 · We have shown that drop breakup in isotropic turbulence is described by a memoryless process whose rate depends only on the Weber number.
