Abstract

This paper aims to numerically simulate the effect of T-shaped spur dike position in a 90 degree bend channel on flow pattern with the rigid bed. The numerical model used in this article is SSIIM. Different positions of spur dike equal to 30, 45, 60 and 75 degrees were selected for a T-shaped spur dike with a ratio of length and wing equals to 1, and it was installed at the outer bank of the channel. The channel had a 2.4 m bend curvature radius. Three dimensional velocity components, SECONDARY FLOW STRENGTH and flow patterns for various positions of spur dike were compared at different levels with Vaghefi’s experimental results. The result showed that SECONDARY FLOW STRENGTH ranges between 12 to 15 percent in a 90 degree bend. The minimum and maximum percentages of secondary flow were consecutively at 30 and 75 degree positions of the spur dike installed.
