Oil-in-water emulsification using confined impinging jets
Journal of Colloid and Interface Science, 2012A 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, 1971INTEREST 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 ...

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, 2022In 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 ...

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.

Modeling Underwater Oil/Gas Jets and Plumes
Journal of Hydraulic Engineering, 1999A 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

The Numerical Study of Oil Drop Jet from Oil-Air Lubrication Nozzle
Advanced Materials Research, 2011Nozzle is an important part of oil-air lubrication system. This paper uses Computational Fluid Dynamics (CFD) software FLUENT to study the flow field of oil air, and different air pressure and nozzle throat size are discussed. The results show that: When air pressure is increased from 0.05Mpa to 0.1Mpa, the maximum diameter (2mm) percentage reduces ...

Underwater oil jet: Hydrodynamics and droplet size distribution
Chemical Engineering Journal, 2016Abstract We conducted a large scale experiment of underwater oil release of 6.3 L/s through a 25.4 mm (one inch) horizontal pipe. Detailed measurements of plume trajectory, velocity, oil droplet size distribution, and oil holdup were obtained. The obtained experimental data were used for the validation of the models JETLAG and VDROP-J.

Steam Jet Pump For Oil Recovery And Reformation
International Oil Spill Conference Proceedings, 2005ABSTRACT 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.
