On Sediment Mass Flux Directionality Induced by Yawed Permeable Vanes under Near-Critical Mobility Conditions
Publisher: ASCE
Abstract: Experiments were conducted in open channel flows under near-critical mobility conditions to quantify local evolution of the sediment bed induced by emergent and submerged rectangular vertical porous walls in yawed conditions. ...
Experimental Tests of Lateral Bedload Transport Induced by a Yawed Submerged Vane Array in Open-Channel Flows
Publisher: American Society of Civil Engineers
Abstract: This work proposes the use of an array of yawed porous vanes to control the lateral bedload transport by locally steering bedform migration and maximize the amount of sediments redirected toward a potential sediment ...
Hydrokinetic Turbines in Yawed Conditions: Toward Synergistic Fluvial Installations
Publisher: ASCE
Abstract: Laboratory experiments were performed in critical mobility conditions to study the effects of an in-stream horizontal axis turbine in yawed conditions. The misalignment between the rotor axis and the incoming flow velocity ...
Aerodynamics of Highway Sign Structures: From Laboratory Tests and Field Monitoring to Structural Design Guidelines
Publisher: ASCE
Abstract: Field- and model-scale experiments were conducted to quantitatively assess the effects of wind loading on Rural Intersection Conflict Warning System (RICWS) highway sign structures. A field-scale RICWS was instrumented ...
CFD and PTV Steady Flow Investigation in an Anatomically Accurate Abdominal Aortic Aneurysm
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: There is considerable interest in computational and experimental flow investigations within abdominal aortic aneurysms (AAAs). This task stipulates advanced grid generation techniques and cross-validation ...
Local Scour around a Model Hydrokinetic Turbine in an Erodible Channel
Publisher: American Society of Civil Engineers
Abstract: Laboratory experiments were performed to study the effect of an axial-flow hydrokinetic turbine model on an erodible channel under both clear water and live-bed conditions. Clear water experiments were performed at two ...
