متن کاملPIV measurements of an air jet impinging on an open rotor-stator system
The current work experimentally investigates the flow characteristics of an air jet impinging on an open rotor-stator system with a low non-dimensional spacing, G = 0.02, and with a very low aspect ratio, e/D = 0.25. The rotational Reynolds numbers varied from 0.33 × 10 to 5.32 × 10, while the jet Reynolds numbers ranged from 17.2×10 to 43×10. Particle image velocimetry (PIV) measurements were ...
متن کاملCfd Analysis of Impinging Axisymmetric Turbulent Fountains
When a positively buoyant vertical fluid jet directed downwards from its source impinges on a horizontal flat surface, the resulting flow is termed an “impinging fountain”. These flows arise in a number of practical situations, for example, in gas metal arc welding (GMAW). Developing a description of this flow presents the researcher with a number of challenges and forms the motivation for this...
متن کاملExperimental Investigation of Impinging Axisymmetric Turbulent Fountains
The behaviour of a turbulent, axisymmetric, Boussinesq, vertical fountain that impinges on a horizontal plate a distance H from the fountain source is investigated. Images from Light Induced Fluorescence visualisation of the flow provide a clear picture of the internal structure of the impinging flow. The interaction between the impinging fountain and the plate results in a buoyant radial wall ...
متن کاملConvective heat transfer predictions in an axisymmetric jet impinging onto a flat plate using an improved k-ω model
The paper shows the results of the convective heat transfer prediction in turbulent axisymmetric jets impinging onto a flat plate using the newest version (2006) of the k-ω turbulence model of Wilcox [1]. Improvements to the heat transfer predictions are obtained in the strongly strained flow regions with the impingement invariant proposed by Manceau [2] together with the F1 function proposed b...
