DEVELOPING TURBULENT FLOWS IN OPEN CHANNELS WITH PILE DIKES

Abstract

This paper presents the developing turbulent flow in open channels with pile dikes by using SDS & 2DH turbulence model, in which the formula for the vertical component of the production of turbulence energy due to the bottom friction and the drag of pile dikes is modified. To test performances of the model, calculation examples are illustrated, and the depth-averaged velocities, vertical vorticity, turbulence energy as well as the Reynolds stress are reproduced reasonably well.
