Digital Simulation of Dominant Eddies of A Co-Flowing Jet
2009This paper described a method for virtual construction of turbulent jet flow field from a limited set of experimental data. The objective is for jet visualization enhancement in near-field plume models. The method is based on the proper orthogonal decomposition (POD), which is an efficient tool to capture the turbulent field based on principal ...

Experimental study of overexpanded co-flowing jets
The Aeronautical Journal, 2008AbstractAn experimental investigation was carried out to find the effect of an annular co-flow jet on the primary supersonic jet from Mach 2 nozzle at different levels of overexpansion. In this study, a convergent-divergent circular nozzle of exit Mach number 2, surrounded by an annular convergent circular nozzle with an annular gap of 4·4mm was used ...

Experimental study of supersonic co-flowing jet
Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2018A detailed experimental study was carried out to investigate the behaviour of a Mach 2 primary jet in the presence of a Mach 1.6 annular co-flow. The lip thickness of the inner nozzle was 7.75 mm. The characteristics of jets were investigated at nozzle pressure ratios 3 to 8, in steps of 1.

Effect of jet velocity in co-flow water cavitation jet peening
Wear, 2016Abstract Water cavitation jet peening (WCP) uses cavitation caused by the shear layer created by two concentric co-flowing jets with large velocity difference to introduce compressive residual stresses in the surface layers of metal components subjected to fatigue loading or a corrosive environment.

Combustion of gaseous coflow jets
Combustion Science and Technology, 2003We present numerical results concerning the combustion that occurs in a three-plan jet system, which represents the two-dimensional version of a coflow gaseous injector of hydrogen and oxygen. The study focuses on the hydrodynamic effects--damped by combustion--that affect the high-speed jets at the entrance of a combustion chamber.

Experimental Investigation of Jet Mixing Mechanism of Co-Flow Jet Airfoil
5th Flow Control Conference, 2010The jet mixing of a co-flow jet (CFJ) airfoil is investigated to understand the mechanism of lift enhancement, drag reduction, and stall margin increase. Digital Particle Image Velocimetry, flow visualization and aerodynamic forces measurements are used to reveal the insight of the CFJ airfoil mixing process.

Liposome Formation Using a Coaxial Turbulent Jet in Co-Flow
Pharmaceutical Research, 2015Liposomes are robust drug delivery systems that have been developed into FDA-approved drug products for several pharmaceutical indications. Direct control in producing liposomes of a particular particle size and particle size distribution is extremely important since liposome size may impact cellular uptake and biodistribution.A device consisting of an

Aerodynamic flow-vectoring of a planar jet in a co-flowing stream
Journal of Fluid Mechanics, 2002The vectoring of an incompressible, two-dimensional jet in a co-flowing stream is investigated by means of direct numerical simulation. The control input used to stimulate jet vectoring is accomplished through distributed suction from blunt-faced lips at the exit of the jet.

Measurements of aerosol product in an axisymmetric co-flow jet
Experiments in Fluids, 2000An experimental investigation explored the effects of varying reactant concentration and Reynolds number on the formation of product in a jet of air/N2/HCl flowing into a co-issuing stream of air/NH3. Turbulent mixing resulted in the production of NH4Cl particles by a chemical reaction with negligible heat release. Laser light was elastically scattered

Autoignition of n-heptane in a turbulent co-flowing jet
Combustion and Flame, 2015Abstract N-heptane autoignition in turbulent co-flowing jets with preheated air is studied using the one-dimensional turbulence (ODT) model. The simulations are designed to investigate the effects of molecular and turbulent transports on the process of autoignition. Both homogeneous and jet configuration simulations are carried out.
