During the past decade particle image velocimetry (PIV) has become a versatile tool in the investigation of flow fields in turbomachinery. In this overview a short summary on recent applications of PIV in these machines is given, with a focus on rotating turbine and compressor test rigs and ...
Particle Image Velocimetry (PIV) is a non-intrusive optical measurement technique which allows capturing several thousand velocity vectors within large flow fields instantaneously. Today, the PIV technique has spread widely and differentiated into many distinct applications, from micro flows over combustion...

A twin-camera stereoscopic system has been developed to extend conventional high image-density Particle Image Velocimetry (PIV) to three-dimensional vectors on planar domains. The stereoscopic velocimeter performs with extremely high accuracy. Translation tests have yielded errors (rms) of 0.2% of full...
摘要: Particle image velocimetry (PIV) is applied here to gaseous and liquid flows including an impinging jet in an atmospheric microburst, gaseous turbulent flow in an internal combustion engine, and turbulent channel flow. The resulting velocity distributions are shown and discussed.关键词:...

Flow in a stirred vessel was investigated using a scanning particle image velocimetry (PIV) system that interrogated the vessel from different aspects using automated placement of camera and light plane. PIV revealed the u , v , and w components in three-dimensional space for the time-averaged ...
Particle Image Velocimetry (P.I.V.) has been used for the analysis of the flow velocities in the outlet part of the impeller and in the vaneless diffuser of a centrifugal pump. Tests have been made in air with the so-called S.H.F. impeller. A lot of experimental and numerical results...
