چکیده مقاله
The bend presence caused changes in flow patterns In the present study, using Fluent software, flow pattern and bathymetery simulated in 120° sharp bend in the four different discharges For verification of the numerical model, first, a 90° sharp bend is simulated and compared with available experimental results Then 120°bend will be evaluated In curved channels, with increasing discharge of flow, the superelevation percentage of the water surface in the section located before the bend is decreasing In the 60° cross section, the dimensionless amount of changes in water level, in discharge 4 5, 9, 12 and 15 liter per second, are respectively, 0 109, 0 108, 0 09 and 0 079 that with the discharge increasing, are ascending In the interior sections of the bend, the transverse slope of the water surface in the inner half width always is greater than outer half width of the channel, So this slope is non linear in sharp bends
