Open channel flow past a curved sluice gate
by Dr Ben Binder, University of Melbourne
Abstract: The problem of free-surface flow past different types of disturbances in an open channel is classical. The disturbances can be: (i) a submerged obstacle on the bottom of the channel; (ii) a step in the bottom of the channel; and (iii) an obstruction in the free-surface. The obstruction in the free surface is usually a plate. This models flows past surfboards, planing hydrofoils and sluice gates. In this talk we discuss new solutions when the obstruction in the free-surface is a curved plate, and compare with the already known results for a flat plate. Fully nonlinear solutions are computed by a boundary integral equation method, and additional weakly nonlinear solutions will be presented.
