RISDiscussion of “Water Distribution System Analysis: Newton-Raphson Method Revisited” by M. Spiliotis and G. Tsakiris
Publisher: American Society of Civil Engineers
Discussion of “Influence of Entrapped Air Pockets on Hydraulic Transients in Water Pipelines” by Ling Zhou, Deyou Liu, Bryan Karney, and Qinfen Zhang
Publisher: American Society of Civil Engineers
Numerical and Experimental Analysis of the Pressurized Wave Front in a Circular Pipe
Publisher: American Society of Civil Engineers
Abstract: This paper focuses on pressurized wavefront behavior and an analysis of trapped air pockets. Flow behavior, trapped air-pocket pressure, and different pressurized wavefront shapes in addition to their propagation conditions ...
Discussion of “Detection of Flood-Prone Areas Using Digital Elevation Models” by Salvatore Manfreda, Margherita Di Leo, and Aurelia Sole
Publisher: American Society of Civil Engineers
Shock-Fitting Approach for Calculating Air Pocket Entrapment Caused by Full Obstruction in Closed Conduit Transient Flow
Publisher: ASCE
Abstract: This paper studies the ability of a Shock-Fitting approach in computing air pocket entrapments in a closed conduit transient flow, caused by suddenly blocking the downstream end. The flow is pressurized at the upstream, ...
New Integrated Condition-Assessment Model for Combined Storm-Sewer Systems
Publisher: American Society of Civil Engineers
Abstract: Optimal assessment of the overall state of the degradation affecting sewer systems requires consideration of both the hydraulic and the structural aspects. This work identifies a set of 15 factors—pertaining to both ...
Optimal Tank Design in Water Distribution Networks: Review of Literature and Perspectives
Publisher: American Society of Civil Engineers
Abstract: Water distribution networks (WDN) are traditionally designed without integrating tanks in the optimization process, despite the numerous benefits tanks bring to network operation. Since 2004, a number of efforts have been ...
A Modified Shock Tracking–Capturing Finite-Volume Approach for Transient Mixed Flows in Stormwater Systems
Publisher: ASCE
Abstract: This paper proposes a modification to a previous shock tracking–capturing approach used for simulating transient flows in stormwater systems. Based on the Godunov-type finite-volume (FV) method, this modified approach uses ...
