Numerical simulation of duct conveying using smoothed particles hydrodynamics

Abstract

A!Js�An efficient smoothed particle hydrodynamics (SPH) method for duet conveying is proposed. We have implemented a lD SPH code for duet conveying, which extends industrial application field of SPH method. The simulation results of lD SPH accord with the experimental results. Numerical simulation results show that major physics of the duet conveying can be well captured in the simulation.The SPH method proposed can be easily extended to deal with many other problems of duet flow if simulation control parameters such as input condition, boundary condition and corresponding equation of state etc. are defined properly.Kl!)'WolYk -slllO Odt etl pmtide /tytlrotlylUlll li cs (SPH); llll mericlll sillll ll llfi o,,; fill et co"veyi/IK; meslt.free metltfHi
