Oil-in-water emulsification using confined impinging jets

Journal of Colloid and Interface Science, 2012
A confined impinging jet mixing device has been used to investigate the continuous sunflower oil/water emulsification process under turbulent flow conditions with oil contents between 5% (v/v) and 10% (v/v). Various emulsifiers (Tween20, Span80, Whey Protein, Lecithin and Sodium Dodecylsulphate) varying in molecular weights have been studied.

Noise Sources in Pressure-jet Oil Flames

Nature Physical Science, 1971
INTEREST in combustion noise in the domestic context has been increasing in recent years because of the more widespread adoption of central heating and the advent of natural gas. Much of the previous work on open turbulent flames has been concentrated on gas/air mixtures1–4whereas Roberts and Leven-thall5 consider the noise of domestic natural gas ...

Steam Jet Pump For Oil Recovery And Reformation

International Oil Spill Conference Proceedings, 2005
ABSTRACT This paper discusses basic performances of the steam jet suction device and its potential application to the spilled oil recovery. The experiments were carried out on suction and ejection performance of the steam-driven jet pump as well as its other benefits such as breaking emulsion or an application to a beach cleaning device.

Jet Pump Testing in Italian Heavy Oils

Proceedings of European Production Operations Conference and Exhibition, 1994
Abstract The paper presents the analysis and the results of the jet pump applications in the two biggest Italian heavy oil fields: Vega (15 °API) in offshore Sicily and Gela (9 °API) in onshore Sicily. In both fields the water cut is as much as 50% and most of the wells produce in artifiCial lifting: ESP, diluent lift and ...

Jet Oil Recovery Device

International Oil Spill Conference Proceedings, 1973
ABSTRACT Emphasis with most contemporary oil recovery schemes is directed toward recovering floating oil in as pure a form as possible at its source. Because of its operating characteristics, the jet oil recovery device described causes contact of jet water streams with the recovered oil and separates the fluids within it.

CFD investigation of air-oil two-phase flow in oil jet nozzle

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2022
In aero-engines applications, nozzle geometric parameters have major effects on the lubricating oil to accurately reach target gears or bearings. To investigate the deviation phenomenon of oil jet flow in the lubrication system, the computational fluid dynamics (CFD) technique integrating with the volume of fluid (VOF) method and SST k- ω turbulence ...

Dispersion of spilled oil by a cavitating jet at sea

Journal of Marine Science and Technology, 2006
This article presents the possibility of using a high-speed water jet for the dispersion of spilled oil at sea. Laboratory experiments showed that a high-speed water jet is very effective in dispersing heavy oil. Two methods were examined and compared using freshwater.

Exploring the complexity in an oil jet falling into an oil bath

2014
An oil stream falling vertically into a stationary bath of the same liquid, if its flow speed is above a critical threshold, because of its viscous property, will induce a transition where a “cusp” on the free surface is “cracked” open by the jet. This industrially important phenomenon has been well studied.

DEVELOPMENT AND TESTS OF AN AIR-JET OIL BOOM1

International Oil Spill Conference Proceedings, 1979
ABSTRACT This paper describes the development of the Air-Jet Boom—a novel boom which has the capability to divert oil slicks under wave and current conditions that normally preclude the deployment of conventional booms. Tests at the EPA's Oil and Hazardous Materials Simulated Environmental Test Tank (OHMSETT) facility have demonstrated ...

Modeling Underwater Oil/Gas Jets and Plumes

Journal of Hydraulic Engineering, 1999
A model is developed for simulating oil spills that initially behave as jets or plumes. The model is based on the Lagrangian integral method. The model can simulate a liquid (oil) in an ambient (seawater), or an oil/gas mixture in seawater. The model considers both shear and forced entrainment. The jet/plume model is combined with two additional models
