Investigation of the Effects of an Inferior Vena Cava Filter and Captured Clot Size on the Hemodynamic Parameters in Non-Newtonian Turbulent Pulsatile Blood Flow

open access: yesApplied Bionics and Biomechanics, 2023
In this computational fluid dynamics (CFD)-based study, the effects of inferior vena cava (IVC) filter implantation on the risk of IVC thrombosis have been investigated using different hemodynamic parameters, including time-averaged wall shear stress ...

Tracking Carotid Artery Wall Motion Using an Unscented Kalman Filter and Data Fusion

open access: yesIEEE Access, 2020
Analyzing the motion of the common carotid artery (CCA) wall yields effective indicators for atherosclerosis. In this work, we propose a state-space model and a tracking method for estimating the time-varying CCA wall radius from a B-mode ultrasound ...

Error of large-eddy simulation in the wall pressure fluctuation of a turbulent channel flow

open access: yesTheoretical and Applied Mechanics Letters, 2021
We analyze the error of large-eddy simulation (LES) in wall pressure fluctuation of a turbulent channel flow. To separate different sources of the error, we conduct both direct numerical simulations (DNS) and LES, and apply an explicit filter on DNS data

Simulation on Soot Oxidation with NO2 and O2 in a Diesel Particulate Filter

open access: yesJournal of Thermal Science and Technology, 2007
Although diesel engines have an advantage of low fuel consumption in comparison with gasoline engines, exhaust gas has more particulate matters (PM) including soot.

Simulation of rough wall turbulent channel flow using a parametric forcing approach [PDF]

open access: yes, 2011
The effects of rough walls on turbulent channel flow are simulated by adding a simple forcing term to the Navier-Stokes equations. An extensive parameter study is used to explore the effects of this term on turbulent channel flow.

Comparison of flow and dispersion properties of free and wall turbulent jets for source dynamics characterisation [PDF]

open access: yes, 2009
The objective of this paper is to provide an investigation, using large eddy simulations, into the dispersion of aircraft jets in co-flowing take-off conditions.

Large scale separation flow control experiments within the German Flow Control Network [PDF]

open access: yes, 2009
This is an overview on flow control experiments for flow separation control conducted in the DNW-NWB atmospheric low-speed wind tunnel performed within the German Flow Control Network. Emphasis is given on the experimental setup using the DLR F15 wall-to-
