Abstract:

A Bingham model is adopted to study the fluid mechanics of mudflows. Equations for predicting the transition from laminar to turbulent flow in an open channel are formulated and verified through experiments conducted in a laboratory flume using Kaolin clay slurry. A theory of uniform turbulent flow in an open channel is developed. The correlation for an empirical turbulence damping parameter is determined using experimental data. Velocity profiles and friction factors predicted by the theory are verified with experimental data.
