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 (

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 ...

Fluids, 2023 Rearrangement events in wall-flow filters lead to the formation of specific deposition patterns, which affect a filter’s pressure drop, its loading capacity and the separation efficiency.

Error of large-eddy simulation in the wall pressure fluctuation of a turbulent channel flow
Theoretical 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
Journal 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]
, 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.

Numerical Simulation on Flow Dynamics and Pressure Variation in Porous Ceramic Filter
Computation, 2018 Using five samples with different porous materials of Al2TiO5, SiC, and cordierite, we numerically realized the fluid dynamics in a diesel filter (diesel particulate filter, DPF). These inner structures were obtained by X-ray CT scanning to reproduce the

High stability in filtration apparatus of African shrimp
iScience, 2023 Summary: The African shrimp (Atya gabonensis) uses elongated setae to filter feed, adapting to high flow velocities. The setae’s stability stems from carefully designed geometric and structural parameters, notably a specialized wall and distribution ...
