چکیده
|
In this research, a bend channel with a 180 degree central angle (curvature
radius to channel width equal to 2) was designed and built in the hydraulic
laboratory of Persian Gulf University in order to help better understand
complicated flow pattern in a sharp bend. Vectrino velocimeter was employed
to measure velocity components and determine bed shear stress. This paper
studied the effect of the length of L-shaped spur dikes on the Reynolds shear
stress variations. The results of such experiments indicated that a 67%
increase in spur dike length would cause bed shear stress to increase by about
53%.
