Structure of into Water Plane Underexpanded Air Jets
An experimental and numerical investigation of the structure of plane underexpanded turbulent air jets in water was conducted to characterize their structure and mixing properties. Measurements included void fraction profiles, static pressure distributions, entrainment rates, and high speed flow visualization. A locally homogeneous flow model was also developed with compressibility effects trea...
متن کاملExhaust of Underexpanded Jets from Finite Reservoirs
The response of anunderexpanded jet to adepletingfinite reservoir is examinedwith experiments and simulations. An open-ended shock-tube facility with a variable reservoir length is used to obtain images of nitrogenand heliumjet structures at successive instances during the blowdown from initial pressure ratios of up to 250. The reservoir and ambient pressures are simultaneously measured to obta...
متن کاملAn entrained Droplet by an underexpanded gas jet into water
When a heat exchanger in a Fast Breeder Reactor cracks, highly pressurized water or steam escapes into the surrounding liquid sodium. A sodium-water reaction then occurs, forming disodium oxide (and hydrogen gas). It can cause secondary damages to the heat exchangers by the reaction heat and erosion corrosion. The released flow of steam from the cracks of the heat exchanger is an underexpanded ...
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 کاملNumerical Study of Interaction of Two Plane Parallel Jets
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...
