Hydraulic jumps and stilling basins [PDF]

open access: yes, 2015
A hydraulic jump is a rapid transition from a high-velocity open channel flow to a slower fluvial motion. It is commonly experienced in streams and rivers, in industrial channels, during manufacturing processes and downstream of dam spillways. The air is

Numerical simulation of flow over a rough bed [PDF]

open access: yes, 2004
This paper presents results of a direct numerical simulation (DNS) of turbulent flow over the rough bed of an open channel. We consider a hexagonal arrangement of spheres on the channel bed.

Characterization of Hydraulic Power in Free-Stream Installations

open access: yesInternational Journal of Rotating Machinery, 2017
The performance of open-channel hydropower devices can be optimized by maximizing the product of their load, hydraulic, and generator efficiencies. The maximum hydraulic power theoretically available must be defined according to the operational scenario ...

Can Ti‐Based MXenes Serve as Solid Lubricants for Brake Applications? A Tribological Study

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores the first implementation of Ti‐based MXenes materials in brake pad friction composite material. The resulting composite material exhibits a 48% reduction in the wear rate; alongside significant improvements are observed for thermal and mechanical properties.

Heat Transfer and Friction in a Low-Aspect-Ratio Rectangular Channel with Staggered Slit-Ribbed Walls

open access: yesInternational Journal of Rotating Machinery, 1998
Fully developed heat transfer and friction in a rectangular channel with slit-ribbed walls are examined experimentally. The slit ribs are transversely arranged on the bottom and top channel walls in a staggered manner.

Experimental and Numerical Investigation of the Effect of Transition Length on Energy Losses in Gradual Transitions Open Channels Under Subcritical Flow [PDF]

open access: yesعلوم و مهندسی آبیاری, 2018
'Transition' is a short hydraulic structure used to change the cross-sectional shape or flow shape. Transitions are commonly used both in the open-channels and natural waterways.
