A particle filter for freeway traffic estimation [PDF]

, 2004
This paper considers the traffic flow estimation problem for the purposes of on-line traffic prediction, mode detection and ramp-metering control. The solution to the estimation problem is given within the Bayesian recursive framework. A particle filter (

In Situ Tracking of Break-up, Resuspension, and Transport of Reactive Particle Structures in a Single Wall-Flow Filter Channel

Emission Control Science and Technology, 2023
Particulate filters are used as a standard component in the exhaust gas aftertreatment of vehicles. The reactive (soot) and inert (ash) particles generated during engine operation are deposited in wall-flow filter.

Evaluation of hemodynamic effects of different inferior vena cava filter heads using computational fluid dynamics

Frontiers in Bioengineering and Biotechnology, 2022
Inferior vena cava (IVC) filters are used to prevent pulmonary embolism in patients with deep vein thrombosis for whom anticoagulation is unresponsive. The head is a necessary structure for an Inferior vena cava filter (IVCF) in clinic use.

Prediction of wall-bounded turbulence in a viscoelastic channel flow using convolutional neural networks

, 2022
Turbulent flow of purely viscoelastic fluids has gained attention in the drag-reduction and flow control communities since a tiny amount of polymer has proven efficient in reducing friction drag in pipe flows.

A Numerical study of resistance in a rough walled channel flow where the ratio of roughness length scale to the depth of flow varies over a wide range [PDF]

, 2009
Numerical calculations were performed over a variety of two-dimensional rib roughness configurations in which the ratio of flow depth to roughness height was varied from 1.1 to 40.

Numerical investigation of detachment and transport of particulate structures in wall-flow filters using lattice Boltzmann methods

Journal of Fluid Mechanics, 2023
The exhaust from combustion engines contains particulate matter (PM), which poses potential health risks to human lungs. Current emission laws place increasingly strict limitations on both PM and particle number, leading to the necessity of using wall ...

Parametric forcing approach to rough-wall turbulent channel flow [PDF]

, 2012
The effects of rough surfaces on turbulent channel flow are modelled by an extra force term in the Navier–Stokes equations. This force term contains two parameters, related to the density and the height of the roughness elements, and a shape function ...
