Molecular dynamics of flows in the Knudsen regime [PDF]

, 2000
Novel technological applications often involve fluid flows in the Knudsen regime in which the mean free path is comparable to the system size. We use molecular dynamics simulations to study the transition between the dilute gas and the dense fluid ...

Chaotic Advection at the Pore Scale: Mechanisms, Upscaling and Implications for Macroscopic Transport [PDF]

, 2016
The macroscopic spreading and mixing of solute plumes in saturated porous media is ultimately controlled by processes operating at the pore scale. Whilst the conventional picture of pore-scale mechanical dispersion and molecular diffusion leading to ...

Elevated atrial blood stasis in paroxysmal atrial fibrillation during sinus rhythm: a patient-specific computational fluid dynamics study

Frontiers in Cardiovascular Medicine, 2023
Introduction Atrial fibrillation (AF) is associated with an increased risk of stroke, often caused by thrombi that form in the left atrium (LA), and especially in the left atrial appendage (LAA).

Computational fluid dynamic prediction of the residence time of a vortex separator applied to disinfection

Water Science and Technology, 2005
A Hydrodynamic Vortex Separator (HDVS) has been modelled using Computational Fluid Dynamics (CFD) in order to predict the residence time of the fluid at the overflow and underflow outlets. A technique which was developed for use in Heating, Ventilation and Air Conditioning (HVAC) was used to determine the residence time and the results have been ...

Hemodynamics analysis and computational fluid dynamics simulations to identify potential location of rupture in abdominal aortic aneurysm

European Heart Journal, 2023
Abdominal Aortic Aneurysm (AAA) rupture is the most severe consequence of aneurysmal disease, with an overall death rate of 80%. Early diagnosis and appropriate follow-up and management of AAA will significantly reduce the risk of rupture and ...
