Periodically arranged co-flowing jets

Journal of Fluid Mechanics, 1994
The problem of a periodic planar arrangement of a large number of co-flowing, interacting jets is investigated. It is shown that this interaction gives rise to strong nearfield oscillations of large-scale spatial coherence and to far-field inhomogeneities.

On Autoignition of Co-Flow Laminar Jets

SIAM Journal on Applied Mathematics, 2016
The authors analyze a mathematical model accounting for the thermal runaway followed by ignition in laminar jets. After a change of variables and unknowns through an adimensionalization process, they consider the system of parabolic equations \(\theta _{\zeta }=\theta _{\xi \xi }+\frac{1}{\xi } \theta _{\xi }\) for \((\xi ,\zeta )\in (0,\lambda )\times

Effect of Eccentricity on Co-flow Jet Characteristics

Iranian Journal of Science and Technology, Transactions of Mechanical Engineering, 2021
Effect of eccentricity on jets delivered from a primary nozzle surrounded by secondary flow is studied experimentally. The eccentricity is achieved by offsetting the annular spacing of the co-flow passage, surrounding the center nozzle generating the primary jet.

Turbulent Jets in Co-Flowing Streams

Journal of the Engineering Mechanics Division, 1979
This paper presents a method for predicting the variation of the velocity and length scales for plane and circular turbulent jets issuing into co-flowing streams. The basis of this method is an assumed variation in the turbulence production integral in the transition region from the strong jet to the weak jet.

Jet Noise Reduction in Co-Flowing Jets with Finite Lip Thickness

International Journal of Vehicle Structures and Systems, 2020
Passive control for suppressing mixing noise from Co-Flowing Jets (CFJ) is presented in this study. The idea behind this is to reduce the convective Mach number of turbulent eddies that produce intense sound radiation. The present study analyses co-flowing jets with a bypass ratio of 6.3 and the primary nozzle lip thickness of 10 mm.

Characteristics of Underexpanded Co-Flow Jets

Applied Mechanics and Materials, 2014
The effect of inner nozzle lip thickness on the co-flow jet characteristics has been studied experimentally. Co-flow nozzles with inner nozzle lip thicknesses of 3 mm and 15 mm have been investigated. The thick-lip nozzle promotes mixing better than the thin-lip nozzle, for all the underexpanded operating conditions. The co-flow nozzle with thin-lip is

Linear stability of co-flowing liquid–gas jets

Journal of Fluid Mechanics, 2001
A temporal, inviscid, linear stability analysis of a liquid jet and the co-flowing gas stream surrounding the jet has been performed. The basic liquid and gas velocity profiles have been computed self-consistently by solving numerically the appropriate set of coupled Navier–Stokes equations reduced using the slenderness approximation.
