.... Editor: Alfonso Ortega. 08 10 2012 24 03 2014 In the present study, laminar pulsating flow over a backward-facing step in the presence of a square obstacle placed behind the step is numerically studied to control the heat transfer and fluid flow. The working fluid is air...

...E. Abu-Nada; A. Al-Sarkhi; B. Akash; I. Al-Hinti Numerical investigation of heat transfer and fluid flow over a backward-facing step (BFS), under the effect of suction and blowing, is presented. Here, suction/blowing is implemented on the bottom wall (adjacent to the step). The finite volume...

...Aya Kitoh; Kazuaki Sugawara; Hiroyuki Yoshikawa; Terukazu Ota Direct numerical simulation methodology clarified the three-dimensional separated flow and heat transfer around three backward-facing steps in a rectangular channel, especially effects of channel expansion ratio ER upon them. ER treated...

...Chao-Kuang Chen; Tzu-Shuang Yen; Yue-Tzu Yang This study applies the lattice Boltzmann method (LBM) to simulate incompressible steady low Reynolds number backward-facing step flows. In order to restrict the simulations to two-dimensional flows, the investigated Reynolds number range is limited...
