Abstract

My research uses Flow 3D model in simulating the flow through the spillway, stirling basin of the Ngan Truoi spillway with two options of reinforced piles on slopes: negative and positive roughness. The Flow 3D hydrodynamic model based on the Navier-Stokes system is an effective tool in simulating the complex hydraulic properties of the flow through irrigation constructions. Calculation results of water level and velocity with 2 different operating conditions are compared with empirical data for both slope dissipation alternatives. In addition the paper also points out the need to add air entrainment models in the simulation of large turbulent flows on hydraulic works as well as select the optimal dissipated obstacles by using numerical model.
