Abstract
Experimental tests and computational tests were performed to analyse discharge coefficients when gates are placed into weir walls. Gate slope and side contraction effect have been considered. A great number of experiments were conducted by considering three angles of inclination of the weir, three shape ratio and three values of the relative opening. Two mathematical equations were obtained, relating the discharge coefficient to the parameters that characterize the phenomenon. Furthermore, computational tests were performed following the Reynolds-Averaged Navier-Stokes (RANS) approach in conjunction with a turbulence closure model. In order to track the fluid surface, the Volume of Fluid algorithm being used. Numerical results have been validated against the experimental showing a good agreement. The validated numerical fluid flow can help to better understand the phenomenon not caught by the experiments.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
