An Enhanced Flux Treatment in Solving Incompressible Flow in a Forward-Facing Step

The aim of this paper is to give a detailed effect of several parameters such as step height, Reynolds number, contraction ratio, and temperature difference between the entrance and solid boundaries, of a forward-facing step. An accurate length of separation and reattachment zones are achieved. A finite-volume method (FVM) has been developed to study incompressible flow in a forward-facing step...

the role of russia in transmission of energy from central asia and caucuses to european union

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...

PIV Study of Flow Separations at a Forward-Facing Step using Long-Range Microscope

The flow separation taking place over the forward-facing step is measured by high-resolution PIV using long-range microscope. The step has height of h=10 mm and the free stream velocity is 20 m/s, resulting in a Reynolds number of Reh=13,700. Two separation bubbles are produced in the immediate upstream and downstream of the step respectively. The upstream separation has a length of 0.6h, while...

Heat Transfer and Turbulent Fluid Flow over Vertical Double Forward-Facing Step

Numerical study of heat transfer and fluid flow over vertical double forward facing step were presented. The k-w model with finite volume method was employed to solve continuity, momentum, and energy equations. Different step heights were adopted for range of Reynolds number varied from 10000 to 40000, and range of temperature varied from 310K to 340 K. The straight side of duct is insulated wh...
