Spatial filtering improved tomographic PIV

Experiments in Fluids, 2013
Tomographic reconstruction accuracy is of fundamental importance to obtain reliable three-dimen- sional three-components velocity field measurements when implementing tomographic particle image velocimetry. Algebraic methods (Herman and Lent 1976) are quite well established to handle the problem in case of high spatial frequency spots on a dark ...

Evaluation of the 3D-PIV standard images (PIV-STD project)

Journal of Visualization, 2000
Particle Imaging Velocimetry (PIV) offers many advantages for studies of fluid flows. Lots of PIV techniques have been developed and applied to various flow fields. However, there are no standard tools for evaluation of the PIV system effectiveness and accuracy. To popularize the PIV for practical use, the PIV system should have some standard.

Acoustic PIV: Measurement of the acoustic particle velocity using synchronized PIV-technique

The Journal of the Acoustical Society of America, 2008
This paper outlines a technique for measuring the acoustic particle velocity and the flow field simultaneously by applying synchronized particle image velocimetry (PIV). As test set-up a squared acrylic glass chamber was chosen. One side of the test section is connected to a loudspeaker, which allows a sinusoidal excitation of the chamber. To point out

PIV recording techniques

1998
In this chapter different approaches to PIV recording are introduced. It is important to realize that the various recording methods are not necessarily defined by the recording medium. The same approach may for instance be applied using either photography or digital recording. The PIV recording modes can be separated into two main branches: (1) methods

Applications: Micro PIV

2018
This section discusses various applications and techniques used in \(\mu \text {PIV}\). The applications include very high spatial resolution measurements of pressure-driven flow in a rectangular capillary and measurements in a challenging toroidal vortex.

Piv-Propsi

Acta crystallographica. Section C, Crystal structure communications
The pseudodipeptide, (S)-N-isopropyl [N-(pivaloyl)pyrrolidin-2-yl]methylaminooxyacetamide, C(15)H(29)N(3)O(3), adopts a global extended conformation with the hydroxylamine group in the g(+)/g(-) structure. The C-terminal amide NH interacts intramolecularly with the hydroxylamine O atom.

Recording Techniques for PIV

2018
Based on the physical concepts of electronic imaging introduced in the previous chapter, this chapter focusses on the image sensor technology in the context of PIV image recording. Loosely based on the historical development of CCD image sensor technology, the chapter describes the advancements such as on-chip intermediate storage, asynchronous ...
