A three-dimensional numerical study of a single droplet splashing vertically on liquid film is presented. The method based the finite volume (FVM) Navier–Stokes equations coupled with fluid (VOF) method, and adaptive local mesh refinement technology adopted. It enables liquid–gas interface to be tracked more accurately, less computationally expensive. relationship between diameter free rim, hei...

Given the problem that droplets cannot stay on surfaces of leaves and wet them effectively, resulting in high levels pesticide input environmental pollution, this work studied dynamic behaviors with different diameters (400–550 um) falling wheat from heights (2–16 cm) using contact angle-measuring instruments a high-speed camera. The VOF method Fluent software was used to establish numerical mo...

the directional response and roll stability characteristics of a partly filled tractor semi-trailer vehicle, with cylindrical tank, are investigated in various maneuvers. the dynamic interaction of liquid cargo with the tractor semi-trailer vehicle is also evaluated by integrating a dynamic slosh model of the partly filled tank with five-degrees-of-freedom of a tractor semi-trailer tank model. ...

multiphase flows are commonly encountered in oil and gas industries. the transport of multiphase flow causes the formation of slug, the increase of pressure drop and the possibility of phase changes therefore, a set of simulation runs was performed to predict flow regimes in a horizontal pipeline, and the results were compared with the baker chart. the effects of small downward inclinations of ...

A novel volume of fluid (VoF) model called explicit diffusion (EVD) is developed for the simulation interfacial flows, including those with turbulence and primary spray atomization. It derived by averaging VoF equations over an explicit, physically-defined length scale. Fluctuations at sub-volume scales, which can arise due to interface dynamics or turbulence, are attenuated process their effec...
