Mechanics of a plant in fluid flow [PDF]

open access: yesJournal of Experimental Botany, 2019
AbstractPlants live in constantly moving fluid, whether air or water. In response to the loads associated with fluid motion, plants bend and twist, often with great amplitude. These large deformations are not found in traditional engineering application and thus necessitate new specialized scientific developments.

Numerical Study on Airfoil Aerodynamics in Proximity to Wavy Water Surface for Various Amplitudes

open access: yesApplied Sciences, 2021
Wing–in–ground crafts will face waves with different amplitudes when flying over the ocean, and the high amplitude situations are especially lack of exploration.

High Temperature Deformation Flow Of A ZK60A Magnesium Alloy After Extrusion

open access: yesArchives of Metallurgy and Materials, 2015
Flow behavior of a ZK60A magnesium alloy after continuous casting and subsequent extrusion was examined in tension at a range of strain rates of 3.0×10−6 − 1.0×10−2 s−1 at temperatures of 473-623K.

Multi-scale flow mechanism and water control strategy of ultra-deep multi-porosity fractured tight sandstone gas reservoirs

open access: yesFrontiers in Energy Research, 2022
The Keshen gas field in the Kuqa Depression, the Tarim Basin, China, contains multiple ultra-deep fractured tight sandstone gas reservoirs with edge/bottom water, which are remarkably complex in geologic structure, with fracture systems at different ...

A NOTE ON THE QUANTUM-MECHANICAL RICCI FLOW [PDF]

open access: yesInternational Journal of Modern Physics A, 2009
We obtain Schrödinger quantum mechanics from Perelman's functional and from the Ricci-flow equations of a conformally flat Riemannian metric on a closed two-dimensional configuration space. We explore links with the recently discussed emergent quantum mechanics.

Relationship between supramaximal flows and flow-limiting mechanisms [PDF]

open access: yesEuropean Respiratory Journal, 1996
The aim of this study was to evaluate the relationship between supramaximal flows (SF) and indices of airway mechanics. We studied 26 asymptomatic young subjects (13 smokers, mean +/- SD 15.9 +/- 6.6 pack-years. Subjects performed maximal expiratory flow-volume (MEFV) curves, according to the American Thoracic Society (ATS) criteria, on a rolling-seal ...

Flow Mechanism of a New Concept Transonic Tandem Fan Stage under the Design and Off-Design Conditions

open access: yesAerospace, 2022
A detailed numerical simulation of a transonic tandem fan stage was conducted, and the change rule of the flow structure inside the fan stage under the design and off-design conditions was discussed to determine the internal flow mechanisms.

Neurocognitive Mechanisms of the Flow State

open access: yes, 2017
While the experience of flow is often described in attentional terms - focused concentration or task absorption - specific cognitive mechanisms have received limited interest. We propose that an attentional explanation provides the best way to advance theoretical models and produce practical applications, as well as providing potential solutions to ...
