Experimental investigation of merging buoyant jets in a crossflow

Creator:: Gregorič, Miroslav
Abstract:: Merging isothermal buoyant jets in a crossflow were investigated experimentally. Jets of salt water were discharged from a constant head tank into the stagnant tap water. A crossflow was simulated by towing the discharge ports through the receiving water at desired speeds. Visualization of the jet cross-sections produced by a...

An experimental/analytical investigation of buoyant jets in shallow water

Creator:: Hsiao, Entsung
Abstract:: This thesis presents the results of an experimental and analytical study of single-port buoyant turbulent jets discharged into shallow water. The experimental results include the measured downstream dilution, centerline concentration and trajectory. Independent parameters considered were Froude number, submerged depth, discharge angle and velocity ratio. Results indicate that decreasing the...

Performance and flow stability characteristics in two-phase confined impinging jets

Creator:: Sabo, Michael D.
Abstract:: Advances in electronics fabrication, coupled with the demand for increased computing power, have driven the demand for innovative cooling solutions to dissipate waste heat generated by these devices. To meet future demands, research and development has focused on robust and stable two-phase heat transfer devices. A confined impinging jet is...

Characterization of the near-field flow structure of an acoustically self-excited jet in a large enclosure using particle image velocimetry (PIV)

Creator:: Tobias, Jason A.
Abstract:: An experimental study of the near-field flow structure produced by an incompressible turbulent Acoustically Self-Excited Jet (ASEJ) in a large enclosure using Particle Image Velocimetry (PIV) is presented. The salient feature of this jet is that it provides an increase in near-field mixing and turbulence without additional external power input....

The effects of pulsing and blowing ratio on a 45° inclined jet in cross flow

Creator:: Stander, Arjan
Abstract:: The effect of jet flow pulsing and blowing ratio on a jet in cross flow has been investigated. Preliminary jet flow studies were performed without cross flow and an extensive study of jet with cross flow was done for a total of nine test cases. The effect of velocities ratios...

CFD simulation of single-phase and flow boiling in confined jet impingement with in-situ vapor extraction using two kinds of multiphase models

Creator:: He, Xiaoliang
Abstract:: With continued development of the electronic industry, the demand for highly efficient heat removal solutions requires innovative cooling technologies. A computational fluid dynamic (CFD) study, including heat transfer, is performed for an axisymmetric, confined jet impingement experiencing boiling and coupled with vapor extraction. Boiling occurs at the target surface while...

Effects of orifice geometry and surface boundary condition on heat transfer of impinging jet array

Creator:: Kanokjaruvijit, Koonlaya.
Abstract:: The effects of the orifice geometry and the surface boundary condition on the heat transfer distribution to a flat surface of an impinging jet array were investigated. The jet array impinged normally onto the surface which was either isothermal or had a uniform heat flux. The experiments were performed for...

Local heat transfer rate and bubble dynamics during jet impingement boiling

Creator:: Mani, Preeti
Abstract:: Characterization of local boiling trends, in addition to the typically reported area-averaged trends, is essential for the robust design and implementation of phase change technologies to sensitive heat transfer applications such as electronics cooling. Obtaining the values of heat fluxes corresponding to locally varying surface temperatures has been a challenge...
