Flow dynamics and mixing processes in hydraulic jump arrays: Implications for channel-lobe transition zones [PDF]
, 2016 A detailed field investigation of a saline gravity current in the southwest Black Sea has enabled the first complete analysis of three-dimensional flow structure and dynamics of a series of linked hydraulic jumps in stratified, density-driven, flows ...

Advanced Engineering Materials, EarlyView.This study investigates the effects of milling parameters, including rotational speed, milling duration, and ball‐to‐powder ratio, on TiAl particle size and morphology in an XHV‐equivalent atmosphere. The creation of oxide‐free surfaces enhances the mechanical properties of green bodies.

Predicting Oxygen Content Downstream of Weirs, Spillways and Waterways [PDF]
, 1995 At hydraulic structures (e.g. weirs, spillways), air-water transfer of atmospheric gases (e.g. oxygen) occurs by self-aeration along the chute and by flow aeration in the hydraulic jump at the downstream end of the structure.

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A
Advanced Engineering Materials, EarlyView.The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

Dissipation of mechanical energy over spillway through counter flow
Građevinar, 2018 A reversed flow in form of cross-jet serves for dissipation of the energy of flow after spillway. Parameters influencing characteristics of hydraulic jump are systematically investigated via a physical model. The obtained results reveal that the reversed

Analytical solution to problems of hydraulic jump in horizontal triangular channels
Ain Shams Engineering Journal, 2013 A hydraulic jump is formed in a channel whenever supercritical flow changes to subcritical flow in a short distance. It can be used in triangular ditch irrigation to raise the downstream water surface.

Characteristics of Undular Hydraulic Jumps: Experimental Apparatus and Flow Patterns [PDF]
, 1995 In open channels, the transition from supercritical to subcritical flows is called a hydraulic jump. For low upstream Froude numbers, free-surface undulations develop downstream of the jump and the hydraulic jump is called an undular jump.

Advanced Engineering Materials, EarlyView.This plot compares experimental tensile stress–strain curves (with 4 different strain rates) and corresponding modelled curves (obtained using the optimised sets of Voce and Miller–Norton parameter values shown). The inferred M‐N values, characterizing the creep, are very similar to those obtained via conventional creep testing.

Numerical and analysis effects of rectangular prism rough beds on hydraulic jumps in open channels
AIP AdvancesHydraulic jumps are characterized by intense turbulence and substantial energy dissipation in open channel flows or stilling basins. This study utilizes the Flow-3D hydraulic computational model, integrating the renormalization group k-ε turbulence model

Journal of Fundamental and Applied Sciences, 2015 This study has for objective to study the theoretical relation of the hydraulic jump by sill, evolving in an U-shaped channel, with a rough bed. Functional relations, in non-dimensional form, relating the jump characteristics, seeming the effect of the ...
