Paper Title:
Numerical Modelling of Multi-Step Energy Dissipation Facility in Rushing Trough
  Abstract

Abstract:Rushing trough is often used as drainage in steep slope section, velocity of flow can be reduced and water-damage of road can also be prevented furtherly if multi-step energy dissipation facility is placed in rushing trough. In this paper, CFD method is adopted and VOF calculating model is established and turbulent kinetic energy and turbulent dissipation rate are introduced as standard to analyse energy dissipation mechanics of the facility. The factors such as height of embankment, gradient of trough, size of step and velocity of flow in inlet, which can influence efficiency of energy dissipation, are also discussed in the paper and regression formula about efficency of energy dissipation is presented. All the conclusion can guide the design of consumed energy facility.
