Abstract: A complete Reynolds-stress transport model of turbulence is used to predict the effects of asymmetry, surface roughness and side-wall inclination on the behaviour of turbulent flows in open, compound, channels. The turbulence model is one which was previously developed with reference to simple, rectangular, open channels and is used here without modification. Comparisons are made with mean-flow and turbulence data from several experiments and these show that the computed results correlate reasonably well with the measured behaviour. The simulations also reveal a hitherto unreported feature of the present flows, namely the noncoincidence at various locations within the flow of the points where the shear stresses and the relevant rates of strain are zero.
