A laboratory Study on the Effect of Perforated Sills in Stilling Basin on the Secondary Depth and Length of the Roller of the Hydraulic Jump

open access: yesعلوم آب و خاک, 2018
The purpose of this study was to evaluate two perforated sills in the stilling basin and their impact on characteristics of the hydraulic jump, such as the length of the roller of hydraulic jump, decrease in the secondary depth of the hydraulic jump, and

An Experimental Study of Hydraulic Jump Due to Moving Jet Impingement [PDF]

open access: yes, 2015
The objective of this project work is to study experimentally the hydraulic jump with a moving jet impingement on a glass plate surface. The jet strikes the horizontally placed glass plate and the jump occur which is investigated with different flow rate

Unified Friction Formulation from Laminar to Fully Rough Turbulent Flow [PDF]

open access: yes, 2018
This paper provides a new unified formula for Newtonian fluids valid for all pipe flow regimes from laminar to fully rough turbulent flow. This includes laminar flow; the unstable sharp jump from laminar to turbulent flow; and all types of turbulent ...

Rapid Sintering of Porous Organic Polymer Powders Into Mechanically Strong Monoliths for Efficient CO2 Capture

open access: yesAdvanced Functional Materials, EarlyView.
Spark plasma sintering enables rapid processing of porous organic polymer (POP) from fine powders to a freestanding and mechanically robust monolith. The sintering process retains the CO2 adsorption capacity and CO2/N2 selectivity, making the monolith more suitable as a solid sorbent for practical carbon capture applications.

Effect of Bed Roughness and Negative Step on Characteristics of Hydraulic Jump in Rectangular Stilling Basin

open access: yesShock and Vibration, 2022
Water flow often releases excess energy after passing through gates and spillways. This energy should be reduced to avoid the destruction of downstream structures. The hydraulic jump, a natural phenomenon, inevitably reduces incoming flow energy.

Hydraulic jumps: Turbulence and air bubble entrainment [PDF]

open access: yes, 2011
A free-surface flow can change from a supercritical to subcritical flow with a strong dissipative phenomenon called a hydraulic jump. Herein the progress and development in turbulent hydraulic jumps are reviewed with a focus on hydraulic jumps operating ...

Experimental Investigation of the Effect of Hydraulic Jump Location on Flow Velocity in Type II Stilling Basin [PDF]

open access: yesعلوم و مهندسی آبیاری, 2014
Hydraulic condition of stilling basin, in particular, the flow rate passing through chute spillway, as well as the location of hydraulic jump plays an important role on velocity fluctuations in a stilling basin.

Free-surface fluctuations and turbulence in hydraulic jumps [PDF]

open access: yes, 2011
A hydraulic jump is the highly turbulent transition between a high-velocity impinging flow and a turbulent roller. The jump flow is characterised by some substantial air bubble entrainment, spray and splashing.

Reconfigurable Magnetic Soft Microrobot for Acoustically Triggered Targeted Bacterial Sterilization

open access: yesAdvanced Functional Materials, EarlyView.
Reconfigurable magnetic soft microrobots integrate in situ‐grown piezoelectric zinc oxide nanorods that produce reactive oxygen species upon acoustic excitation. Combining magnetically guided transport with thermally induced planar reconfiguration, the microrobots achieve targeted delivery and enhanced bacterial sterilization through efficient on ...
