| Abstract | ||||
| Air impingement jet into main cross stream is countered in numerous modern applications, for example, dryers, pneumatic conveying and spot cooling. The common impact between the jet and the cross stream is analyzed at various jet to cross flow velocity ratio. In the present study, an air jet is impinged at an assortment of velocity ratios into a cross stream. The cross stream is brought out through a 10cm diameter pipe with Reynolds number reaches out 6 104. At the diverse conditions, the flow pattern is simulated numerically with two-equation turbulent models of Realizable k- , SST k- and RSM. The outcome demonstrates that the jet pattern is altogether misshaped as the standard speed is expanded and detachment regions are created. Greater state of turbulent intensity and stresses is seen in the regular face between the stream and cross stream. | ||||
