An adequate supply of dissolved oxygen (DO) is essential for the survival of aquatic organisms. Hydraulic structures can increase DO levels by creating turbulent conditions where small air bubbles are...
Effect of Wall Shear Stress Distribution on Manning Coefficient of Smooth Open Rectangular Channel Flows
Open channel flow Manning friction coecient Wall shear stress
2009/10/12
The determination of velocity distribution in open channel flows is crucial in many critical engineering problems such as channel design, calculation of energy losses and sedimentation. In this study,...
Plastic Mechanism and Elastic Analyses in the Strength Estimation of an Axially Compressed-Thin-Walled Channel Steel Section Beam
Channel section local buckling plastic mechanisms effective width moment capacity and axial-compressive strength
2009/2/18
This paper presents the study of an analytical model to estimate the strength of a thin-walled channel steel section beam subjected to axial-compressive loads. The model is based on two different meth...
DEVELOPMENT OF 3D FLAW DETECTION SYSTEM WITH MULTI-CHANNEL PLANAR ARRAY PROBES AND 3D SAFT ALGORITHMS
multi-channel planar array probe synthetic aperture focusing technique beam-spread angle three-dimensional defects
