RISNew Method to Calculate Friction Velocity in Smooth Channel Flows Using Direct Numerical Simulation Data
Publisher: American Society of Civil Engineers
Abstract: In this paper, we leverage the direct numerical simulation (DNS) data for closed-channel flow for a range of friction Reynolds number (Reτ∼180–5,000) to develop a new one-point friction velocity method (OPFVM) to calculate ...
Some Insights on Flow over Sharp-Crested Weirs Using Computational Fluid Dynamics: Implications for Enhanced Flow Measurement
Publisher: ASCE
Abstract: This study reexamines flow over a sharp-crested weir using computational fluid dynamics (CFD) to identify the optimal operating range under which the weir functions with accuracy as a free-flowing measurement device. A ...
A Novel and Enhanced Calibration of the Tilting Weir as a Flow Measurement Structure
Publisher: ASCE
Abstract: A large collection of laboratory measurements of piezometric head (h) and discharge (Q) were made over hydraulic models of a tilting weir at nine different angles, ranging from 25.7° to 90° within a 0.3-m-wide flume. These ...
