| Abstract |
A numerical model is presented for calculating flows, in compound prismatic channels with turbulence-driven secondary motion. The model uses the algebraic stress turbulence model developed by Launder and Ying and the κ-ε model along with the continuity and momentum equations. The model is tested by application to an open channel flow and a duct flow. Satisfactory predictions are obtained on the distributions of mean velocities and shear stresses opposing the primary velocity, while the anisotropy of normal stresses is underestimated by one order of magnitude less than the experimental data.
