SPH numerical investigation of the characteristics of an oscillating hydraulic jump at an abrupt drop

收藏本文  分享

This paper shows the results of the smooth particle hydrodynamics(SPH) modelling of the hydraulic jump at an abrupt drop,where the transition from supercritical to subcritical flow is characterised by several flow patterns depending upon the inflow and tailwater conditions. SPH simulations are obtained by a pseudo-compressible XSPH scheme with pressure smoothing; turbulent stresses are represented either by an algebraic mixing-length model, or by a two-equation k-ε model. The numerical model is (本文共计8页)......[继续阅读本文]
