Stability estimate for scalar image velocimetry

open access: yesJournal of Inverse and Ill-posed Problems, 2023
Abstract In this paper, we analyze the stability of the system of partial differential equations modelling scalar image velocimetry. We first revisit a successful numerical technique to reconstruct velocity vectors u

Feature Tracking Velocimetry Applied to Airborne Measurement Data from Murg Creek

open access: yesE3S Web of Conferences, 2018
A new image feature tracking velocimetry is presented and tested on airborne video data available from a previous study at Murg Creek (Canton Thurgau, Switzerland). Here, the seeded flow scenery had been recorded by an off-the-shelf action camera mounted

Single camera three component planar velocity measurements using two-frequency planar Doppler velocimetry (2ν-PDV) (2012) [PDF]

open access: yes, 2006
Two-frequency planar Doppler velocimetry (2ν-PDV) is used in conjunction with imaging fibre bundles to make time-averaged three component velocity measurements using a single CCD camera and iodine cell. In this scheme the flow is sequentially illuminated

Image processing technique for hydraulic application

open access: yesТруды Института системного программирования РАН, 2018
In this paper, we present techniques Surface Flow Image Velocimetry (SFIV) that is a practical extension of Particle Image Velocimetry method (PIV). In particular, this technique is to evaluate the behavior on the surface flow for complex flow.

Particle image velocimetry studies of bubble growth and detachment by high speed photography

open access: yes, 1997
An understanding of bubble flows is important in the design of process equipment, particularly in the chemical and power industries. In vapour-liquid processes the mass and heat transfer between the phases is dominated by the liquid-vapour interface and ...

Stereo Digital Particle Image Velocimetry Investigation of a Free Surface Mixing Layer [PDF]

open access: yes, 2005
Shear flows in the vicinity of a free surface are a problem with numerous applications, perhaps the most obvious being the wakes of seagoing surface vessels.

Microfabricated Anisotropic Myobundles for the Scalable Production of Cardiac Tissue Grafts

open access: yesAdvanced Functional Materials, EarlyView.
Controlling the anisotropy of cardiac tissue remains an outstanding challenge in the field of cardiac tissue engineering. Here, we introduce an approach to generate anisotropic cardiac myobundles using cell‐adhesive, synthetic, electrospun fibers and stem cell‐derived cardiac fibroblasts.

Application of digital particle image velocimetry to insect aerodynamics: measurement of the leading-edge vortex and near wake of a Hawkmoth [PDF]

open access: yes, 2007
Some insects use leading-edge vortices to generate high lift forces, as has been inferred from qualitative smoke visualisations of the flow around their wings.

Particle Imaging Velocimetry with Color-Encoded Illumination: A Review

open access: yesSensors
High-resolution and three-dimensional measurements at large scales represent a crucial frontier in flow diagnostics. Color-encoded illumination particle imaging velocimetry has emerged as a promising non-contact volumetric measurement technique in recent
