NUMERICAL SIMULATION OF SIDEWALL AND BED SLOPE EFFECTS ON DENSITY FLOW THICKNESSNader Barahmand and Mehrzad JahanpoorAbstract Dense flows are created from volumetric mass difference between two fluids. Though their movement, dense flows often join from a small riverine section to a larger reservoir or oceanic section. Therefore this study seeks to calibrate a common numerical model, Fluent using experimental outcomes and then to simulate density flow behavior in canals with convergent sidewalls. Results indicate that fluent software was properly successful in simulating the density flow behavior of such conditions, using turbulent model Kε of RNG type. According to the results, increase in convergence angle of canal walls would lead to an increase in density flow thickness. Meanwhile, for a constant divergence angel increasing in the slope value causes an increase in flow thickness.
