Paper Title
Reduction Of Primary Re-Circulation Loss Zones For Expanded Flows

Abstract
Reduction in recirculation zone size in suddenly expanded geometries is one of the major issues to deal with. After the flow encounters the sudden expansion geometry like flow over rear side of any automobile, acquires many complex features like separation, re-circulation, attachment and reverse flow. These flow phenomena effect the performance of the automobile on the mileage basis. In the present study, flow over such geometries with blowing and suction scenario is studied for different Lmax/Lmin models, namely 3, 4 and 5. For Lmax/Lmin = 5, it is found that the re-circulation and loss zones are more. Further, the configuration of Lmax/Lmin = 5 is subjected to different operating conditions like blowing and suction. For further improvement, blowing is done at different heads of pressure, like 200 mm and 300 mm of water. With suction, flow scenario is completely changed and attachment point is observed at the base of the model itself. Results thus identify the improved flow structure that can be useful to different applications like power generation in wind or gas turbines.
