متن کاملThe effect of the angle upper edge in shaped noise barriers with a T-shaped upper edge
Background and Objective: Efforts to improve the effectiveness of noise barriers have been made, including shape, aesthetics, form and gender. Therefore, the aim of this study was to investigate the effect of the angle upper edge in shaped noise barriers with a T-shaped upper edge. Materials and Methods: A 2D boundary element method (BEM) was used to predict the insertion loss of the tested ba...

In recent years, a considerable number of such poles have failed duc to heavy build-up of ice on the lines. These failures may be attributed to the accuracy or reliability of the design methods and/or to the lack of adequate experimental information to evaluate the crit...
متن کاملLocal and Global Friction Factor in a Channel with V-Shaped Bottom
This paper presents an experimental research on the distribution of local friction factor, fb, and global friction factor, f, over the cross-section of a channel with V-shaped bottom, which typically occurs in sewers and culverts. Several series of experiments were conducted for measuring velocity and boundary shear stress. It is found that, Darcy-Weisbach, f, is more sensitive than other resis...
