Effects of Electrical Boundary Configurations on Magnetohydrodynamic Flow and Heat Transfer in a Liquid Metal-filled Annulus [PDF]

open access: yesJournal of Applied Fluid Mechanics
This numerical study investigates magnetohydrodynamic (MHD) flow and heat transfer for liquid metals within a cylindrical annulus subjected to a radial magnetic field.

Pressure Loss Estimation of Three-Phase Flow in Inclined Annuli for Underbalanced Drilling Condition using Artificial Intelligence [PDF]

open access: yesJournal of Chemical and Petroleum Engineering, 2017
Underbalanced drilling as multiphase flow is done in oil drilling operation in low pressure reservoir or highly depleted mature reservoir. Correct determination of the pressure loss of three phase fluids in drilling annulus is essential in determination ...

Hyponormality on an annulus with a weight

open access: yesMathematical Methods in the Applied Sciences, 2020
In this work, we consider the hyponormality of Toeplitz operators on the Bergman space of the annulus with a logarithmic weight. We give necessary conditions when the symbol is of the form , where ψ and φ are analytic on the annulus .

Numerical investigation of horizontal magnetic field effect on the flow characteristics of gallium f

open access: yesJournal of Thermal Engineering, 2021
In the present numerical study, the effect of an external horizontal magnetic field on the natural convection of an electrically conducting molten metal (gallium) inside a vertical cylindrical crucible has been investigated.

The Skein Category of the Annulus

open access: yes, 2021
We construct the skein category $\mathcal{S}$ of the annulus and show that it is equivalent to the affine Temperley-Lieb category of Graham and Lehrer. It leads to a skein theoretic description of the extended affine Temperley-Lieb algebras. We construct an endofunctor of $\mathcal{S}$ that corresponds, on the level of tangle diagrams, to the insertion

Global algebraic Poincaré--Bendixson annulus for van der Pol systems [PDF]

open access: yes, 2021
By means of planar polynomial systems topologically equivalent to the van der Pol system we demonstrate an approach to construct algebraic transversal ovals forming a parameter depending Poincar'e-Bendixson annulus which contains a unique limit cycle for

Early Body Mass Index z‐Score Change and Resolution of Severe Malnutrition in Children With Sickle Cell Anemia in a Low‐Income Setting: A Prospective Single‐Arm Extension Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell anemia (SCA) in low‐income settings are at risk of severe malnutrition, but optimal nutritional management has not been established. We evaluated an intensified ready‐to‐use therapeutic food (RUTF) regimen in children with persistent severe malnutrition after initial treatment and assessed whether early ...

Central Nervous System Tumors Among Infants in Canada: A Report From CYP‐C

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) tumors in infants are rare, pose unique clinical challenges, and lack large‐scale evidence‐based data to guide management. This study seeks to describe CNS tumors in Canadian infants and to compare their outcomes with those of older children.

Curling of a Heated Annulus [PDF]

open access: yes, 2016
We study the large-displacement behavior of a thin annulus subjected to thermal gradients. Following axisymmetrical deflections, the annulus buckles into a periodic mode shape, which eventually forms a number of a radial curls under sustained heating. We

Numerical Simulation and Experiment on Flow Field in Horizontal Tubing-Casing Annulus with a Tubing Coupling

open access: yesShiyou jixie, 2023
Accurate prediction of annulus pressure loss is vital for drilling and completion of deep and ultra-deep wells.Research on flow field in annulus is theoretically fundamental to prediction of annulus pressure loss.To reveal the flow field of the ...
