Numerical simulations are used to study an under-expanded sonic jet injected into a supersonic crossflow and an over-expanded supersonic jet injected into a subsonic crossflow. A finite volume compressible Navier–Stokes solver developed by Park & Mahesh (2007) for unstructured grids is used. The flow conditions are based on Santiago et al.’s (1997) and Beresh et al.’s (2005) experiments for son...

Turbulent scalar mixing in the near field of a tee mixer (transverse jet in a pipe) is studied using Particle Image Velocimetry (PIV) and Planar Laser Induced Fluorescence (PLIF). Two jet-to-pipe velocity ratios, r = 3.06 and r = 5.04, are investigated for a turbulent pipe flow at a Reynolds number of 20,850. The laser measurement techniques are described, typical flow structures in the near fi...

The turbulent/non-turbulent interface of a jet is characterized by sharp jumps ('discontinuities') in the conditional flow statistics relative to the interface. Experiments were carried out to measure the conditional flow statistics for a non-isothermal jet, i.e. a cooled jet. These experiments are complementary to previous experiments on an isothermal Re=2000 jet, where, in the present experim...

Steep topography on the ocean bottom, when underneath an oscillating tide, is not only associated with significant internal wave generation at the tidal frequency but also nonlinear flow features, large overturns and turbulent flow. Here, we investigate the internal wave dynamics and turbulence at an isolated steep obstacle using a three-dimensional, high-resolution large eddy simulation (LES)....

A new analytical approach is presented for analysis of two-particle azimuthal correlations in heavy ion collisions at relativistic energies. This approach suggests that elliptic flow measured by experiment has a compound structure, namely, that it may come from superposition of several components. General expressions have been derived for the two-particle correlation function isolating the cont...

Electrochemical flow cells have found widespread use in analytical chemistry due to their short response time, high sensitivity and selectivity [1, 2]. The geometrical flexibility and therefore, the ease of coupling the electrochemical to other experimental techniques has attracted considerable interest for applications in electrocatalytic research as well. Such coupling is far more cumbersome ...

A jet pump is a type of pump that accelerates the flow of a secondary fluid (driven fluid) by introducing a motive fluid with high velocity into a converging-diverging nozzle. Jet pumps are also known as adductors or ejectors depending on the motivator phase. The ejector's motivator is of a gaseous nature, usually steam or air, while the educator's motivator is a liquid, usually water. Jet pump...
