Flow structure and optical beam propagation in high-Reynolds-number gas-phase shear layers and jets [PDF]

, 2001
We report on the structure of the scalar index-of-refraction field generated by turbulent, gas-phase, incompressible and compressible shear layers and incompressible jets, and on associated beam-propagation aero-optical phenomena.

Hydrodynamics affected by submerged vegetation with different flexibility under unidirectional flow

Frontiers in Marine Science, 2023
Submerged vegetation changes the hydrodynamic characteristics of rivers, lakes, wetlands, and coastal zones. However, only a few studies have focused on the effect of flexible submerged vegetation on hydrodynamic characteristics under unidirectional flow.

Influence of the axial fan blade angle on the turbulent swirl flow characteristics [PDF]

Scientific Technical Review, 2014
The paper presents the investigation of the turbulent swirl flow in a pipe behind the axial fan with adjustable nine blades for the angles of 22°, 26° and 30° for the same rotation number (1500 rpm). Velocities were measured with laser Doppler anemometry

Spiral structures in turbulent flow [PDF]

, 1993
Spiral structures are natural candidates for the role of the ‘generic structures’ of turbulent flow, because they are the eventual outcome of Kelvin-Helmholtz instability, an all-pervasive phenomenon associated with nearly all shear flows at very high Reynolds number.

The Interaction of High-Speed Turbulence with Flames: Global Properties and Internal Flame Structure

, 2011
We study the dynamics and properties of a turbulent flame, formed in the presence of subsonic, high-speed, homogeneous, isotropic Kolmogorov-type turbulence in an unconfined system.

Selection of a Suitable Wall Pressure Spectrum Model for Estimating Flow-Induced Noise in Sonar Applications

Shock and Vibration, 1995
Flow-induced structural noise of a sonar dome in which the sonar transducer is housed, constitutes a major source of self-noise above a certain speed of the vessel.

A keystone Methylobacterium strain in biofilm formation in drinking water [PDF]

, 2017
The structure of biofilms in drinking water systems is influenced by the interplay between biological and physical processes. Bacterial aggregates in bulk fluid are important in seeding biofilm formation on surfaces.

Defective flow space limits the scaling up of turbulence bioreactors for platelet generation

Communications Engineering
To complement donor-dependent platelets supplies, we previously developed an ex vivo manufacturing system using induced pluripotent stem cell (iPSC)-derived expandable immortalized megakaryocyte progenitor cell lines (imMKCLs), and a turbulent flow ...

Numerical simulation of turbulent flow between shrouded contra-rotating disks

Advances in Mechanical Engineering, 2016
The turbulent flow between shrouded contra-rotating disks was numerically studied with a two-layer turbulence model and a modified Launder–Sharma low-Reynolds number k - ε model.

Turbulent Heat Transfer over roughness: a comprehensive review of theories and turbulent flow structure

International Journal of Thermofluids
Turbulent heat transfer over rough surfaces is crucial in natural and industrial processes, yet it has received less attention than that of momentum transfer.
