Therefore, a specialized study on the fundamental process during the jet breakup is believed to be an effective approach. The aim of this paper is to understand the fundamental process of hydrodynamic interaction of jet breakup and droplet formation Using the immiscible liquid-liquid system, water and silicon oil as the test fluids Cited by: 1. Breakup of multiple jets in immiscible liquid-liquid systems: A computational fluid dynamics study In this study, the formation of droplets from multiple circular nozzles into an immiscible. Highlights Breakup modes of an axisymmetric, laminar compound jet of immiscible fluids in a coflowing system are numerically studied. A front-tracking/finite difference method is used. Three modes: inner dripping–outer dripping, inner jetting–outer jetting and mixed dripping–jetting are found. Transition from dripping to jetting is investigated by varying various by: A liquid being ejected from a nozzle emanates from it as discrete, uniformly sized drops when the flow rate is sufficiently low. In this paper, an experimental study is presented of the dynamics of a viscous liquid drop that is being formed directly at the tip of a vertical tube into ambient air. The evolution in time of the drop shape and volume is monitored with a time resolution of 1/12 to.
the drop formation of such jets. This work also includes a numerical solution of the momentum equations in cylindrical coordinates. From the experimental work, a modification to existing theoretical equations has been made to account for the existance of local maxima in the length of laminar jets as their velocity is increased. dynamics model in order to study the confined co-flowing jet formed at low Reynolds numbers in a 2D flow focusing device. When two immiscible fluids flow in a flow focusing device, either monodisperse droplets or parallel flows are obtained depending upon the flow rate of . The formation of drops of particulate suspensions composed of spherical, neutrally buoyant, noncolloidal particles in a viscous liquid is examined experimentally. The suspensions are investigated over a range of particle volume fractions, φ=nπd p 3 /6 where n is the particle number density and d p is the particle diameter (d p =– μ m in most of the experiments), and for flow through. Numerical study on the blending of Immiscible Liquids in static mixer Domenico Daraio The present work is focused on a better understanding of both mixing processes in static mixer for immiscible liquids (oil-in-water emulsion) and the most important parameters affecting the mixing performance. In .
Two problems involving radial laminar jets of immiscible liquids are considered: a free radial slit jet and a jet on a rotating disk. An asymptotic method of solution is proposed that makes it possible to determine the flow parameters far from the source. The difference between these flows and those of homogeneous liquids is demonstrated. Transition from laminar to turbulent flow for the liquid-jet in a liquid rotating crossflow as compared to a liquid–gas study (Eggers, ). The solid horizontal line is the critical Re j for transition of the jet from laminar to turbulent flow, as reported by Madabhushi et al. () in their study of liquid jets in gaseous crossflow.
