Variational 3D-PIV with sparse descriptors [PDF]

Measurement Science and Technology, 2018
Abstract 3D particle imaging velocimetry (3D-PIV) aims to recover the flow field in a volume of fluid, which has been seeded with tracer particles and observed from multiple camera viewpoints. The first step of 3D-PIV is to reconstruct the 3D locations of the tracer particles from synchronous views of the volume.

Studies on Velocity Fields Around the Cavitation Vortices Generated by the Model of a Rotating Blade

Polish Maritime Research, 2018
The elimination of hazards caused by cavitation phenomena is an important issue to be considered in the design of process equipment including flow machinery. These hazards are: cavitation erosion, efficiency decrease as well as vibration and noise.

Flow Field of Turbulent Premixed Combustion in a Cyclone-Jet Combustor

Journal of Thermal Science and Technology, 2007
The flow field in highly turbulent premixed combustion has been examined, using a cyclone-jet combustor. The shear-strain rate is obtained by PIV system. Results show that, in combustion field, mean axial velocity does not decay along center axis and RMS

Developing Soft Interconnected Microchannel Network for 2D Skin‐Like Actuator

Advanced Science, EarlyView.
A soft interconnected network of microchannels is proposed to develop new pneumatic actuators for future bio‐inspired soft robots. Simultaneous stimulation of this network generates regional asymmetric strains in walls of microchannels whose interaction across the entire surface leads to bending curvatures in multidimensions.

Amphibious Movement of Microrobots Inspired by Water Spiders

Advanced Science, EarlyView.
Inspired by the water strider, a novel microrobot is designed to maintain amphibious mobility in complex environments. It retains the ability to traverse the air‐liquid interface and perform directional movement within sophisticated, multifaceted environments, including complex gastric wall structures, with precise controllability.

Quantification of the Influence of Particle Voids on PIV Measurements via Synthetic-PIV [PDF]

, 2021
Particle Image Velocimetry (PIV) is an important technique to investigate complex flow fields but limited to the tracking fidelity of the flow tracers and the uncertainties in the evaluation process. To examine these issues this work implements a physic-based motion simulation for small spherical particles, serving as flow tracers in PIV, with existing

Beyond Probiotics: Postbiotics for Healthy Aquaculture

Advanced Science, EarlyView.
This critical review assesses limitations of probiotics and proposes postbiotics, preparations of inanimate microorganisms and their metabolites, as a more stable, controlled, and biosafe formulation. Postbiotics offer significant advantages during industrial aquafeed production and storage. However, their practical implementation is currently hindered

Spatial and Temporal Variation of Turbulence during Oscillatory Flow in Realistic Model Human Airways

Journal of Fluid Science and Technology, 2012
Turbulence in the oscillatory flow in realistic model human central airways was measured by particle image velocimetry (PIV) to reveal the nature of turbulence in a lung. The transparent silicone model of multi-branching airways was fabricated from X-ray
