Lebanon has been considered a sample of Europe in the Middle East, and it is surprising to have an Islamic resistance against Israel in this small modern country. The Islamic Resistance was, at the beginning, portrayed as having a very different ideology from that of the neighboring countries of the Middle East. This Resistance was established on the basis of being a resistance model for the fr...

PURPOSE This study aims to present flow control over the backward-facing step with specially designed right-angle-shaped plasma actuator and analyzed the influence of various scales of flow structures on the Reynolds stress through snapshot proper orthogonal decomposition (POD). METHODS 2D particle image velocimetry measurements were conducted on region (x/h = 0-2.25) and reattachment zone in...

in this paper, the effects of baffle on thermal characteristics of combined convection-radiation heat transfer in laminar flow adjacent to an inclined backward facing step (bfs) in a horizontal duct are investigated. a baffle is mounted on the top wall of channel downstream side of step. in this study, the fluid is treated as a gray, absorbing, emitting and scattering medium; therefore, in the ...

In this paper, we perform a direct numerical simulation study to investigative the effect of compressibility on the flow over a backward-facing step. A spectral multidomain method is used for simulating the compressible flow at Reynolds number of 3000 over an open backward-facing step. The role of compressibility in the sub-sonic regime is studied by simulating the flow at different free-stream...

We study the cavitating flow over a backward facing step with an incompressible polydisperse cavitation model. The model can predict experimental observations for this reasonably well, including shedding cloud characterized by condensation front, cavity length, void fraction, and frequency. All variations produced cavities, but turbulence grid resolution are essential better predictions, delaye...
