Prediction of Fluid Flow and Heat Transfer Characteristics Behind a Single Backward-Facing Step
Numerical solutions based on standard finite volume method are presented for the study of heat transfer and fluid dynamic characteristics in turbulent flows behind a single sided backward-facing step. The calculation of the differential equations is performed using SIMPLE algorithm. For the turbulent quantities standard K-model is used. Predicted mean velocity profiles and reattachment lengths ...
متن کاملMultivariable Closed-loop Control of the Reattachment Length Downstream of a Backward-facing Step
Active control of separated flows has become a major challenge in recent years. Whereas most of the work published so far is based on simulation studies this paper gives an example of a successful application of a multivariable closedloop flow control in wind tunnel experiments. A robust H∞-controller is used to control the spanwise reattachment length downstream of a benchmark problem, a so-ca...
متن کاملExperimental Investigations of Supersonic Flow around a Long Axisymmetric Body
A series of supersonic wind tunnel tests on an ogive-cylinder body were performed to investigate the pressure distribution, the boundary layer profiles, and the flow visualization at various angles of attack. All tests were conducted in the trisonic wind tunnel of the Imam Hossein University. The theoretical shock angle at different model positions compared well with those we obtained via Schi...

متن کاملAn 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...
