| Résumé : | The effect of side mass injection on turbulent flow with axial entry to a circular duct in the form of centrally confined jet has been investigated. A standard κ-ε model modified for streamline curvature has been used for detailed analysis following a comparison with a κ-ω model for some test cases. Results show that flow stabilization and relaminarization could occur due to the side injection. The predicted recirculation zone, friction factor, total turbulent energy, turbulent shear stress, Taylor scale Reynolds number, and turbulent energy flux show gradual reduction with increase in the side injection velocity. |
