- Abstract
In order to study the hydrodynamic characteristics of porous plate, a CFD numerical calculation model of the complex pervious deflector can be established by the porous medium model, Darcy's law and least squares method. The similarities and differences between the porous medium model and three-dimensional orifice plate were analyzed. The comparison showed that the porous medium model had certain rationality and feasibility. On this basis, a fluid-solid coupling model of a full-scale water channel with a porous medium model was established. The numerical results show that the support truss can meet the strength requirements; the maximum displacement is 3.25 mm, which can ensure the porous permeable deflector flatness. Moreover, the existence of a reversed flow in the water diversions enables the drifting diversion device to have a certain self-cleaning ability while blocking a certain volume of dirt entering the water outlet.
