Simulation and Visualization of Flows Laden with Cylindrical Nanoparticles in a Mixing Layer

Journal of Nanotechnology, 2018
The motion of cylindrical particles in a mixing layer is studied using the pseudospectral method and discrete particle model. The effect of the Stokes number and particle aspect ratio on the mixing and orientation distribution of cylindrical particles is

Field-Relevant High Stokes Number Study of Particle Impacts in High-Speed Compressor via Engine Test

Aerospace
Exposure of propulsion gas turbines to inlet flow contaminated with dust, sand, or ash particulates can lead to a myriad of complex and interrelated damage modes that reduce engine operational life, increase maintenance costs, and pose a safety risk to ...

FSI—vibrations of immersed cylinders. Simulations with the engineering open-source code TrioCFD. Test cases and experimental comparisons

Comptes Rendus. Mécanique, 2022
In this paper, we assess the capabilities of the Arbitrary Lagrangian–Eulerian (ALE) method implemented in the open-source code TrioCFD to tackle down two fluid–structure interaction problems involving moving boundaries.

The number of degrees of freedom of three-dimensional Navier–Stokes turbulence [PDF]

Physics of Fluids, 2009
In Kolmogorov’s phenomenological theory of turbulence, the energy spectrum in the inertial range scales with the wave number k as k−5/3 and extends up to a dissipation wave number kν, which is given in terms of the energy dissipation rate ϵ and viscosity ν by kν∝(ϵ/ν3)1/4.

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

FEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Low Mach Number Limit of the Full Navier-Stokes Equations [PDF]

Archive for Rational Mechanics and Analysis, 2005
The low Mach number limit for classical solutions to the full Navier Stokes equations is here studied. The combined effects of large temperature variations and thermal conduction are accounted. In particular we consider general initial data. The equations leads to a singular problem, depending on a small scaling parameter, whose linearized is not ...

NAVIER–STOKES EQUATIONS ON THE β-PLANE [PDF]

, 2012
Mathematical analysis has been undertaken for the vorticity formulation of the two dimensional Navier–Stokes equation on the β-plane with periodic boundary conditions. This equation describes the flow of fluid near the equator of the Earth. The long time

Augmenting and Assaying Nav1.1 Protein Quantity for Dravet Syndrome Therapy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Dravet Syndrome (DS) is a developmental and epileptic encephalopathy predominantly caused by heterozygous loss‐of‐function variants in SCN1A, which encodes Nav1.1. Conserved upstream open reading frames (uORFs) in SCN1A were validated to regulate translation in reporter assays, demonstrating the therapeutic viability of increasing Nav1.1 from ...

Refined saddle-point preconditioners for discretized Stokes problems [PDF]

, 2016
This paper is concerned with the implementation of efficient solution algorithms for elliptic problems with constraints. We establish theory which shows that including a simple scaling within well-established block diagonal preconditioners for Stokes ...

Extending Service Beyond Active Duty: Generalizability of Rheumatoid Arthritis Research Conducted Among U.S. Veterans

Arthritis Care &Research, Accepted Article.
Biomedical research involving United States Veterans continues to advance healthcare beyond the Veterans Health Administration. This is particularly true in rheumatoid arthritis (RA), where Veteran‐centric research has uncovered novel insights into pathogenesis, risk factors, and disease manifestations, informing clinical care and research across both ...
