Abstract

Combined with design and test data of a low head sluice, CFD software and RNGturbulence model were used to simulate three-dimensional flow of sluices stilling basin. The original design has been optimized by adjusting the layout of the stilling basin. In connection with typical operating conditions, the calculated results such as sluice discharge capacity, flow pattern, velocity distribution, and the water surface line are more consistent with the observations of the physical model. Further analysis based on turbulent energy distribution in stilling basin, the energy dissipation rate, reveals that the two stilling basin can improve energy dissipation efficiency of water jump with low Froude number. Optimization scheme is effective and feasible, and it also provides a good reference for future mathematical model for the design and optimization of such works.
