Reference experiment on aerosol particle transport for dynamic situations [PDF]

, 2023
To study airborne transport of aerosol particles by mixed convection and dynamic situations within a closed room, the Cottbus Aerosol Particle Reference Experiment (CARE) was built and equipped, which includes thermal manikins and a spreader dummy.

An Introduction to Particle Acceleration in Shearing Flows

Galaxies, 2019
Shear flows are ubiquitously present in space and astrophysical plasmas. This paper highlights the central idea of the non-thermal acceleration of charged particles in shearing flows and reviews some of the recent developments.

Assessing and Modelling the Interactions of Instrumented Particles with Bed Surface at Low Transport Conditions

Applied Sciences, 2021
Sediment transport at near threshold to low transport stages (below the continuous transport) can still be affected by flow turbulence and its dynamics can benefit from further comprehensive studies. This study uses an instrumented particle embedded with

Surrogate Modelling for High-speed Rotating Flow Fields Based on Multi-fidelity Data Fusion

Journal of Isotopes
High-speed rotating flow fields play a pivotal role in the mechanical systems used for stable heavy isotopes. The high dimensional design space of such complex rotating machinery is characterized by strong nonlinearity and substantial parameter coupling.

Injection of Deformable Capsules in a Reservoir: A Systematic Analysis

Fluids, 2019
Motivated by red blood cell dynamics and injectable capsules for drug delivery, in this paper, a computational study of capsule ejection from a narrow channel into a reservoir is undertaken for a combination of varying deformable capsule sizes and ...

Spatial Vulnerability: Bacterial Arrangements, Microcolonies, and Biofilms as Responses to Low Rather than High Phage Densities

Viruses, 2012
The ability of bacteria to survive and propagate can be dramatically reduced upon exposure to lytic bacteriophages. Study of this impact, from a bacterium’s perspective, tends to focus on phage-bacterial interactions that are governed by mass action ...

Mechanisms of Inertial Particle Transport in Compressible Wall Turbulence: The Role of Compressibility-modified Coherent Structures [PDF]

Journal of Applied Fluid Mechanics
Particle-laden compressible turbulence plays a key role in industrial and aerospace applications. This study investigates the near-wall transport behavior of inertial particles in compressible channel turbulence using direct numerical simulation (DNS ...

Phase coherence of solar wind turbulence from the Sun to Earth

Frontiers in Astronomy and Space Sciences, 2023
The transport of energetic particles in response to solar wind turbulence is important for space weather. To understand charged particle transport, it is usually assumed that the phase of the turbulence is randomly distributed (the random phase ...
