The self-resonating water jet offers the advantages of both a cavitation jet and a pulsed jet, and thus has been widely used for many practical applications. In the present study, the 120◦ -impinging edge Helmholtz nozzle was investigated for better erosion performance. The oscillating mechanism was analyzed from both numerical and experimental perspectives. The results showed that the cavitati...

Background. In clinical color Doppler examinations, mitral regurgitant jets are often observed to impinge on the left atrial wall immediately beyond the mitral valve. In accordance with fluid dynamics theory, we hypothesized that a jet impinging on a wall would lose momentum more rapidly, undergo spatial distortion, and thus have a different observed jet area from that of a free jet with an ide...

A moving metallic plate subject to heating and cooling boundary conditions is considered in this work. The plate is heated by an imposed heat  ux, and cooled down by an array of impinging jets through convection and radiation. The objective of the present work is determination of operating conditions for controlling the temperature distribution at the end of both heating and cooling sections. ...

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 ...

Jet impingement has immense applications in industrial cooling, such as glass tempering, turbine blades, electrical equipment, etc. The interplay in-between several jet arrangements and the effect of swirl intensity require enormous study to achieve steady heat transfer. This paper numerically investigates an inline array 25 circular confined swirling air jets impinging vertically on a flat sur...
