A Lattice Boltzmann Model for the Simulation of Flows in Open Channels with Applications to Flows in a submerged sluice gate

Abstract : Numerical simulations of free surface flows are important to provide a prediction tool for the optimal management of irrigation canals. Here we consider an alternative to solving the shallow water equations. We propose a free surface model in which the vertical component of the water current is fully resolved. We believe that such a detailed description can be useful to model the °ow around gates or in other situations where the vertical structure of the °ow will be important such as in the case of sediment transport and deposition. Our approach is based on a two-fluid Lattice Boltzmann model. We compare the predictions obtained from numerical simulation and experiments performed on a laboratory micro-canal facility.
