Multilayer Velocity Model Predicting Flow Resistance of Aerated Flows Down Grass-Lined Spillway
Publisher: ASCE
Abstract: Grass-lined spillways are flow conveyance structures with environmental benefits. The stability of such spillways has been typically assessed considering soil erosion, but the design of grass-lined spillways based on ...
Self-Aeration and Flow Resistance in High-Velocity Flows Down Spillways with Microrough Inverts
Publisher: American Society of Civil Engineers
Abstract: Free-surface aeration is a key characteristic of high-velocity flows on spillways. Despite their common use as conveyance structures, there is a research gap in the understanding of flows across spillways with small invert ...
Drag Reduction in Aerated Chute Flow: Role of Bottom Air Concentration
Publisher: ASCE
Abstract: Wall shear stress modification in self-aerated flows has been observed in boundary layer–type flows mainly in the form of drag reduction. Due to its complexity, drag reduction has predominantly been studied using experimental ...
