Application correlation algorithm to create a new critical depth equation for gradually varied flow in trapezoidal channel using teaching–learning and studying [PDF]

open access: yesJournal of Hydraulic Structures, 2020
The critical depth is a hydraulic factor of the flow, it plays a particularly important role in studying and designing for open channels, especially during identification of water surfaces and analyzing to determine the phenomenon of a hydraulic jump in ...

The critical layer in sheared flow [PDF]

open access: yes17th AIAA/CEAS Aeroacoustics Conference (32nd AIAA Aeroacoustics Conference), 2011
Critical layers arise as a singularity of the linearized Euler equations when the phase speed of the disturbance is equal to the mean flow velocity. They are usually ignored when estimating the sound field, with their contribution assumed to be negligible. It is the aim of this paper to study fully both numerically and analytically a simple yet typical

Experimental Determination of the Flow Coefficient for a Constrictor Nozzle with a Critical Outflow of Gas

open access: yesFluids, 2023
Reduction of energy expenditures required for various technological processes is a pressing issue in today’s economy. One of the ways to solve this issue in regard to liquefied natural gas (LNG) storage is the recovery of its vapours from LNG tanks using

New empirical correlation for oil flowrate prediction through chokes [PDF]

open access: yesJournal of the Serbian Chemical Society, 2020
Accurate prediction of choke restricted multiphase flowrate is always interesting in oil industry in the absence of flowmeters for field production monitoring and management purposes.

Critical review of global plastics stock and flow data

open access: yesJournal of Industrial Ecology, 2021
The production, consumption, and waste of plastics have been rapidly growing worldwide in the last decades. A variety of data are needed to characterize plastics stocks and flows across space, time, and life cycle to derive insights for developing ...

Behavior of information flow near criticality [PDF]

open access: yesPhysical Review E, 2021
Recent experiments have indicated that many biological systems self-organize near their critical point, which hints at a common design principle. While it has been suggested that information transmission is optimized near the critical point, it remains unclear how information transmission depends on the dynamics of the input signal, the distance over ...

Critical flow velocities in cohesive saline soils [PDF]

open access: yesE3S Web of Conferences, 2021
The article discusses the issue of determining non-erosion velocities for cohesive saline soil at the bottom and slopes of canals. Based on the formulas of Ts.E. Mirtskhulava for the determination of non-eroding velocities of water flow in cohesive soils,
