Immersed Boundary Projection Method for Boundaries With Slip Velocities

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
A formulation of the immersed boundary method for incompressible flow over arbitrarily‐shaped bodies with surface slip described by the Navier boundary condition is presented. The wall slip velocity and the boundary force are determined implicitly through a projection to satisfy both the boundary condition and the divergence‐free condition of the ...

Unsteady cooperative flow in compression system

open access: yesPropulsion and Power Research, 2012
When there are several bodies with relative motion in a flow field, such as the flow in the compression system of modern aero-engine, the flow field will have certain special features, one of which is that the time-space structure of such multi-bodies ...

On the Variability of Results for Cylinder Flow: A Systematic Analysis of Parameter Sensitivity Within the Lattice Boltzmann Method

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
This study systematically investigates the variability of cylinder flow results. We provide a comprehensive overview of literature values and, using the lattice Boltzmann method (LBM), show that insufficient convergence studies and variations in simulation parameters are a plausible cause for the significant spread in data.

A simplified two‐station approach for modeling metabolism in dam tailwaters subject to diel flow variation

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Tailwaters are ubiquitous and highly managed ecosystems whose food webs often rely disproportionately on autochthonous energy. In situ continuous dissolved oxygen data are increasingly being used to estimate gross primary productivity and ecosystem respiration in rivers, but this approach is complicated in tailwaters, where upriver ...

Market Interviews in Shared Traumatic Reality: A Trauma‐Informed, Co‐Constructed Framework

open access: yesPsychology &Marketing, EarlyView.
ABSTRACT Qualitative market interviews may become trauma‐sensitive when ordinary questions about consumption, work, finance, mobility, identity, professional continuity, or institutional trust intersect with displacement, insecurity, loss, or ongoing threat.

Unsteady mhd free convection flow of casson fluid past over an oscillating vertical plate embedded in a porous medium

open access: yes, 2015
This article studies the unsteady MHD free flow of a Casson fluid past an oscillating vertical plate with constant wall temperature. The fluid is electrically conducting and passing through a porous medium.
