Hydraulic Forces on a Wicket Gate Under Upstream Quasi-Laminar Flow. An Experimental Analysis Technique

Abstract

The two-dimensional potential theory of hydrodynamics is used to model the steady-state component of water flow approaching a gate aperture controlled by hydraulic wicket gates in a lock and dam system. The steady-state pressure against a typical wicket gate partially closing the aperture is then modeled using a conformal mapping technique in the complex plane. The elastic reaction at the supporting prop of the gate is derived from dynamic equilibrium considerations. The analytical results compare very well with the experiments conducted on a 1/25-scale physical model. A simple second-moment formulation allows the statistical characterization of response parameters for practical applications to design.
