A jet of fluid discharging into a cross stream, also known as Jet In Crossflow (JICF), has received many experimental and numerical investigations. In addition to the fundamental understanding of threedimensional mixing and shear flow characteristics, the fluid dynamics research community often regarded it as a benchmark test case for validating turbulence models. Although many authors consider...

A jet flowing in the Kelvin wave propagation direction along the seaward side of a continental slope is found to decrease in strength as it leaks mass onto the continental shelf. As a result, a shelf break jet flowing in the opposite direction is induced on the shelf. The combination of these two flows creates a decaying, high-pressure tongue centered about the shelf break. An idealized, reduce...

In the present work, a numerical simulation of two parallel turbulent jets was performed. The simulations were carried out by using the  standard, the  standard and the RSM models. A parametric study was also presented to determine the effect of the nozzles spacing and velocity ratio on the axial and transverse positions of the merge and combined points. Correlations between the various paramet...

The nanoparticle transportation and Brownian diffusion in planar jet flow is simulated via large eddy simulation in this work. To thorough compare the Brownian diffusion with different particle size, we computed three particle diameter dp = 1 nm, 10 nm and 50 nm in one simulation process simultaneously. The numerical results showed that at the flow developing stage, the particle mass concentrat...

In Pelton turbine, the energy carried by water is converted into kinetic energy by providing nozzle at the end of penstock. The shape of jet affects the force and torque on the bucket and runner of turbine. The nozzle of circular cross section is commonly used. In this paper attempt has been made to study the effect of four different jet shapes on the flow and torque characteristics of Pelton t...

The recent tomo-PIV technique is presented and apply to a pulsed jet in cross-flow. This technique gives the instantaneous three-dimensional velocity field in a fat sheet (typically the depth of the measurement volume is a tenth of the other dimensions). The results presented here show the applicability of the technique to the characterization of a complex three-dimensional flow.

In this study, modeling of a fuel jet which has been injected by high pressure into a low-pressure tank are investigated. Due to the initial conditions and the geometry of this case and similar cases (like CNG injectors in internal combustion engines (ICE)), the barrel shocks and Mach disk are observed. Hence a turbulence and transient flow will be expected with lots of shocks and waves. Accord...
