| Abstract | ||||
| The present work is concerned with an experimental investigation of flow and Heat transfer through a fence located in an asymmetric plane two-dimensional diffuser. The average velocity and fluctuation fields have been measured with a constant temperature hot-wire anemometer (CTA). However, pressures in reversed flow regions have been measured using 5-hole-probe. Of special interest is the influence of the fence on measuring the velocity and the pressure of the flow in relation with heal faster parameters at five well-chosen stations of the diffuser. The obtained experimental data are used to provide a comparison between the cases of using and not using the fence for the sake of separation control and Consequently the determination of the variation of Stanton and Nusselt numbers, particularly in the separated regions. Also, the investigation is reported for some attributes about the sensitivity of the separated and reversed flow regions, that represent a range of flows in which the controlling mechanisms are largely unknown | ||||
