Laser Doppler anemometry measurements of a confined turbulent water jet with a uniform background flow
… turbulent water jet with several very slow, coflowing external streams was measured with a frequency shifted laser Doppler anemometer. The objective was to approximate a jet submerged in an ambient fluid of infinite domain by using a confined jet in a uniform coflow. The coflow prevents flow …

Numerical simulation of mixing processes in two-dimensional channel flows
… calculations of a jet -discharging into a coflowing stream correspond satisfactorily with numerical and experimental results of other investigators. The mixing part of the numerical model is verified using analytical solutions of simplified mixing processes and experimental results obtained …

Jet Fluid Mixing Control Through Manipulation Jet Fluid Mixing Control Through Manipulation of Inviscid Flow Structures
… in order to enhance mixing in the near field of coflowing, subsonic, turbulent, free jet flows. The characteristics of the concentration field and the mixing performance are examined, mainly in quantitative manner. Two new parameters, mixing index and mixing efficiency index, are defined for free …

Numerical Investigation of Liquid Film Dynamics and Atomisation in Jet Engine Fuel Injectors
… form via an airblast-type fuel injector. A coflowing high-speed airstream destabilises the liquid fuel, which is thus sprayed into fine droplets into the combustion chamber. The prediction of this phenomenon for various operating conditions relevant to the aeronautical industry requires a …

Collective hydrodynamics of soft microparticles in quasi-two-dimensional confinement
… ordered and manipulated with external forces or coflowing streams, but these methods can be limited in generality and scalability. New techniques to control particle trajectories would enable new applications in such areas as materials assembly, optofluidics, and miniaturized "on-chip" bioassays …

An Experimental Study of Soot Formation in Dual Mode Laminar Wolfhard-Parker Flames
An experimental study of sooting characteristics of laminar underventillated ethylene non-premixed flames in hot vitiated environments was performed using a modified Wolfhard-Parker co-flowing slot burner. The burner could be operated in "single mode" with a cold air/oxygen mixture as the oxidizer …
