Entrainment Characteristics of Turbulent Round Gas Jets Submerged in Water
The entrainment process in two-phase buoyant jets differs significantly from their singlephase counterparts, and is not well understood. Entrainment models developed for singlephase flow are often used in two-phase jetting simulations, albeit with limited success. In this work, Particle Image Velocimetry (PIV) and shadowgraph flow visualization experiments have been conducted on submerged round...
متن کاملHeat Transfer Characteristics of Swirling Impinging Jets
Impinging jets are used in a wide number of industrial cooling applications due to their high heat and mass transfer abilities. The current research is concerned with the effect of swirl on the heat transfer characteristics of jet impingement cooling. Two inserts were designed order to generate swirling flow. These two designs, “Swirl Insert A” and “Swirl Insert B”, were tested at various Reyno...
متن کاملexperimental investigation of atomization of water jets in air streams
atomization is a process by which a volume of liquid is converted spray. this process includes the breakup of the liquid jet or the liquid sheet exiting the injector. this paper has experimentally investigated the models and mechanisms for the breakup of the liquid jet and the liquid sheet formed by the jets impingement in a still environment and in an environment with counter flow, coflow, and...
متن کاملDesigning and Manufacturing the Multiple Jets Simulator and Experimental Investigation of the Multiple Jets in Crossflow
Designing and manufacturing the multiple jets simulator and experimental investigation of the multiple jets in crossflow at low velocity ratios have been studied Together with design and build a low-speed wind tunnel. A specific rake is used to determine the flow field pressure and changes in static pressure measured by pressure taps in the near field of the jets. There are generally three regi...
متن کاملEffects of Upward Seepage on Depth of Scour Hole Downstream of Free Falling Jets Under Constant Tail Water Depth
rade control structures are used to control bed erosion in steep small rivers mostly in the mountains. Scour downstream of this structure can lead to failure. Over the past years, the effect of different variables on this phenomena have been studied, however the effect of upward seepage which is common due to head difference of the banks water table or water surface level between the upstream a...
