Numerical Simulation Of The Water-sediment Two Phase And Structure Optimization Research In The Shuttle-conical Tube

The turbid flow isolation device—shuttle conical tube (referred to as the shuttle conical tube) is anew separation of the two-phase flow of water and sediment patented technology. In order to supplementand improve the dynamic hydraulic shuttle conical tube separation mechanism of water and sediment, andoptimize its structure type. In this paper, The results of this study on the basis of the previousone,Application of theoretical analysis, experimental research and numerical simulation to verify andcomplement each other’s approach to study that Two-phase flow of water and sediment characteristics andstructure type optimization principles in the Shuttle-conical tube.Through the Numerical simulation of water and sediment two-dimensional two-phase flowfield,Get the sediment hydrostatic settlement process of velocity distribution and the distribution regularityof concentration in the Shuttle-conical tube and Ordinary device,which with the same structure size. Theresults were analyzed and compared, Reveals the Shuttle-conical tube in water and sediment separationefficiency is superior to the ordinary device. Through three-dimensional numerical simulation,For differentinto traffic and different inlet sediment concentration of the uniform and non-uniform sand sand tonumerical simulation in the Shuttle-conical tube. Get the full details of the flow characteristics, and Revealthe spindle taper pipe hydraulic separation mechanism of water and sediment. Through the numericalsimulation of the non-uniform sand, Get the distribution regularity of different particle size of sedimentand the excision rate in the Shuttle-conical tube.On different angle of Shuttle-conical tube、dip of Cone Circle、dip of under the cone、 position ofCone Circle and water distribution pipe of installation position set up30different Shuttle-conical tubemodels, By two-dimensional and three-dimensional numerical simulation of two-phase flow of water andsediment, Comparative analysis similarities and differences of velocity field、concentration field and whichimpact on the separation efficiency of water and sediment in different models. To complement and perfectthe structure optimization principles of the Shuttle-conical tube, which can provide instructions for makingoptimization in the structure or operation conditions. which can provide instructions for useing in actualand optimization in the structure.
