Experimental investigation on cross flow fan’s casing parameters inside of a split air conditioner indoor unit by Stereo Particle Image Velocimetry
Özgün Özer,Dilek Kumlutaş +1 more
TL;DR: In this paper, the flow effects of a cross flow fan (CFF) casing inside of a split air conditioner (SAC) were parametrically investigated, where Volute curvature, tongue angle, vortex wall angle and vortex wall distance to the CFF were selected as the investigation parameters.

Acoustic particle velocity measurements: a cross comparison between modern sensor technologies
TL;DR: In this paper, a cross comparison between two measurement techniques is performed in order to measure acoustic particle velocity, which can be performed in any sound field and does not depend on a large anechoic room.

Digital Particle Image Velocimetry
Christian Willert,Morteza Gharib +1 more
TL;DR: In this article, the directional ambiguity associated with PIV and LSV is resolved by implementing local spatial cross-correlations between two sequential single-exposed particle images, and the recovered velocity data are used to compute the spatial and temporal vorticity distribution and the circulation of the vortex ring.

Determination of displacements using an improved digital correlation method
TL;DR: An improved digital correlation method is presented for obtaining the full-field in-plane deformations of an object by numerically correlating a selected subset from the digitized intensity pattern of the undeformed object.

Fundamentals of digital particle image velocimetry
TL;DR: In this paper, the measurement principle of digital particle image velocimetry (PIV) is described in terms of linear system theory and conditions for PIV correlation analysis as a valid interrogation method are determined.
