Numerical simulation study on spread angle in oblique cut flip bucket

With the advantages of simple structure, good energy dissipation effect and so on, sky jump is widely used in water conservancy project. But at present, prediction about range free nappe not complete. The studies show that ejection angle different locations outlet section, but specific distribution section velocity still unclear. measurement mostly direct measurement, how to accurately control difficult, no systematic study has been made. Especially, on diffusion width are few, understanding enough. In this article, deflection degree flow lateral direction quantified by spread angle. Studied characteristic through numerical simulation. results characteristics maximum value affected change flip bucket size approach condition, presented a set equations for calculating
