Effect of Angle of Impact on Dynamic Pressure of the Flip Bucket Jets

Effect of Angle of Impact on Dynamic Pressure of the Flip Bucket Jets

In this study, dynamic pressures due to impact of a ski jump out of a flip bucket downstream of a chute spillway model have been studied. Experiments were performed for five discharge (0.11, 0.18, 0.25, 0.32, 0.39 mP<sup>3</sup>P/s per unit width) and four jet impact angles (0P<sup>...
