Meta‐Lens Particle Image Velocimetry
Advanced Materials, 2023AbstractFluid flow behavior is visualized through particle image velocimetry (PIV) for understanding and studying experimental fluid dynamics. However, traditional PIV methods require multiple cameras and conventional lens systems for image acquisition to resolve multi‐dimensional velocity fields. In turn, it introduces complexity to the entire system.

Boundary-Layer Meteorology, 2013
A method for measuring the two-dimensional distribution of wind velocity vectors near a surface exposed to solar radiation, by tracking brightness temperature images instead of particle images, is proposed. It is based on time-sequential thermography with the algorithm used for particle image velocimetry. This thermal image velocimetry (TIV) was tested

The Journal of the Acoustical Society of America, 2020
We review a technique that we developed that combines shadowgraph or schlieren imaging with image processing tools to study the sound produced by turbulent shear flows. These flows are challenging acoustically because they are characterized by a distributed cloud of correlated sources that produce sound through multiple mechanisms.

Applied Optics, 1988
A new technique, digital image velocimetry, is proposed for measurement of instantaneous velocity fields of time dependent flows. A time sequence of single-exposure images of seed particles are captured with a high speed camera, and the sampled images are then digitized on an image processor, enhanced, and superposed to construct a multiple-exposure ...

Particle image velocimetry (PIV), also called particle image displacement velocimetry (PIDV), is a method of whole flow field velocimetry, which is currently causing a lot of interest. This methodrelies on the recording of particle positions in a section of the flow at a given instant in time. The measurement region may be defined by a thin laser sheet

Seedless Velocimetry Measurements by Schlieren Image Velocimetry
AIAA Journal, 2011Schlieren optical systems have been used to perform velocity measurements in refractive turbulent flows using particle image velocimetry algorithms. This schlieren image velocimetry (schlieren "particle image velocimetry") technique makes use of naturally occurring refractive turbulent eddies in a flow as virtual "seed particles" upon which velocimetry

Moving fluids have always been an object of fundamental physical research. An understanding of the dynamic behavior of streaming liquids and gases is the basis for disciplines in engineering ranging from the design of aircraft and ships to harbor development, wavebreaker projects, cavitation erosion, or sound production and attenuation.
