Fluid simulation in a cyclone reverse circulation well washing device based on computational fluid dynamics [PDF]

open access: goldEnergy Science & Engineering, 2019
This paper instructs the working principle of the well washing device and its parameter optimization in practical applications. A fluent fluid engineering simulation software was used to establish the calculation model of the bottom flow field. The fluid

Computational Fluid Dynamics for Brain Circulation and Aneurysm with Therapeutic Devices [PDF]

open access: greenInterventional Neuroradiology, 2004
We analysed fluid dynamics at brain arteries having multiple inflow and out flow like Willis ring based on clinical imaging modalities. In addition, we analysed fluid dynamics with therapeutic devices like coils and stents to simulate their influences to blood flow. 3D CTA and MRA obtained three-dimensional structures of the brain vessels.

On the mathematical fluid dynamics of the atmospheric Walker circulation [PDF]

open access: hybridMonatshefte für Mathematik, 2022
AbstractStarting from the general, governing equations for a viscous, compressible fluid, with an associated description of its thermodynamics, we outline an asymptotic derivation based on the thin-shell approximation. [The details appear in another publication.] This produces a reduced system of equations which retain all the dynamics and ...

A Computational Fluid Dynamics Study of the Extracorporeal Membrane Oxygenation-Failing Heart Circulation

open access: bronzeASAIO Journal, 2020
Extracorporeal membrane oxygenation (ECMO) is increasingly deployed to provide percutaneous mechanical circulatory support despite incomplete understanding of its complex interactions with the failing heart and its effects on hemodynamics and perfusion.

Computational fluid dynamics prediction and validation of gas circulation in a cheese-ripening room [PDF]

open access: greenInternational Dairy Journal, 2006
This paper discusses the application of a computational fluid dynamics (CFD) approach to predicting air velocity patterns and circulation of an exogenous gas inside a pilot cheese-ripening room in 3 dimensions (3D). Comparison of numerical results with experimental data showed a fairly close agreement in the qualitative prediction and a few ...

Crustal dynamics of Mount Vesuvius from 1998 to 2005: Effects on seismicity and fluid circulation [PDF]

open access: bronzeJournal of Geophysical Research: Solid Earth, 2008
This paper presents the results of hydrogeochemical and seismological studies carried out at Mount Vesuvius during the period June 1998 to December 2005. Hydrogeochemical data show the occurrence of slowly varying long‐term variations in the total dissolved salts and bicarbonate contents of the groundwaters, accompanied by a general decline in water ...

Cell-Driven Fluid Dynamics: A Physical Model of Active Systemic Circulation [PDF]

open access: green
Active fluid circulation and transport are key functions of living organisms, which drive efficient delivery of oxygen and nutrients to various physiological compartments. Because fluid circulation occurs in a network, the systemic flux and pressure are not simple outcomes of any given component. Rather, they are emergent properties of network elements

Time Course of the Dynamics of Cerebrospinal Fluid Circulation in Hypertensive Intracerebral Hemorrhage

open access: bronzeNeurologia medico-chirurgica, 1984
The dynamics of cerebrospinal fluid (CSF) circulation in 20 cases with hypertensive intracerebral hemorrhage was estimated with radioisotope cisternography (RIC) using In-111-DTPA. CT scan was performed simultaneously to observe the changes in the intracranial pathologies.

Simulation and optimization of airlift external circulation membrane bioreactor using computational fluid dynamics [PDF]

open access: greenWater Science and Technology, 2014
The airlift external circulation membrane bioreactor (AEC-MBR) is a new MBR consisting of a separated aeration tank and membrane tank with circulating pipes fixed between the two tanks. The circulating pipe is called a H circulating pipe (HCP) because of its shape.
