Study on visualization of water mixing flows in a digester equipped with a vertical impeller by using radiotracers

open access: yesNuclear Engineering and Technology, 2020
A mixer with a new concept design has been adapted into water treatment plants. It reportedly cuts down the energy consumption of the mixer by the new mixer, which moves vertically and creates internal flows toward its bottom.

Influence of Wall Deformation Structure on the Liquid Film Flow Behavior Under Turbulent Conditions

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT To explore the influence of typical wall deformation structure in the scrubbing‐cooling tube on the liquid film, this paper studied the liquid film flow behavior on the riblet walls with representative riblet radii and compared them with the flat wall. Under different liquid film Reynolds numbers (Rel = 8.3 × 103 ~ 3.14 × 104), the liquid film

Experimental study of the flow field in patient specific lower airways [PDF]

open access: yes, 2009
In this study Particle Image Velocimetry (PIV) is used to visualize and measure airflow in the lower airways. Using Rapid Prototyping Manufacturing (RPM) technology, a hydraulic in vitro model was developed and constructed.

Performance prediction of point-based three-dimensional volumetric measurement systems [PDF]

open access: yes, 2008
Point-based three-dimensional volumetric measurement systems are defined as multi-view vision systems which reconstruct a three-dimensional scene by first identifying key points on the views and then performing the reconstruction.

Near-wall nanovelocimetry based on Total Internal Reflection Fluorescence with continuous tracking

open access: yes, 2014
The goal of this work is to make progress in the domain of near-wall velocimetry. The technique we use is based on the tracking of nanoparticles in an evanescent field, close to a wall, a technique called TIRF (Total Internal Reflection Fluorescence ...

Large-scale instabilities in a STOVL upwash fountain [PDF]

open access: yes, 2005
The fountain flow created by two underexpanded axisymmetric, turbulent jets impinging on a ground plane was studied through the use of laser-based experimental techniques. Velocity and turbulence data were acquired in the jet and fountain flow regions
