Acoustic treaming visualization in elastic spherical cavities

Flow visualizations are presented for acoustic streaming occurring inside spherical elastic cavities oscillating in an acoustic field. Streaming flows are visualized using Particle Image Velocimetry (PIV) and results are observed for a range of values of a dimensionless frequency parameter, M =120-306. Over the frequency range investigated, streaming flow fields remain steady at a given value o...

Particle tracking velocimetry and particle image velocimetry study of the slow motion of rough and smooth solid spheres in a yield-stress fluid.

We report experimental evidence of an effect opposite to the "solidification" of small bubbles in liquid where the surface can become immobile. Namely, it is demonstrated that smooth solid spheres falling in a yield-stress fluid under the action of gravity can behave similar to drops. Particle tracking velocimetry was used to determine the shape of the yielded region around solid spherical part...

How to optimize intracardiac blood flow tracking by echocardiographic particle image velocimetry? Exploring the influence of data acquisition using computer-generated data sets.

AIMS Echocardiographic particle image velocimetry (EPIV) has been used for tracking contrast-enhanced intracavitary blood flow. Little is known, however, how basic imaging parameters (line density, frame rate, contrast bubble density) affect the quality of such tracking results. Our study aimed at investigating this by using simulated echo data sets. METHODS AND RESULTS A computational three-...

Stereo Particle Tracking

Particle Tracking Velocimetry (PTV) has become a standard technique frequently applied in flow field diagnostics ([1],[7],[8]). This article presents a novel technique which combines the strength of well known 2-D PTV with stereo calibration and correlation techniques to obtain 3D Lagrangian velocity fields. The here presented stereo correlation technique is fundamental for 3-D PTV. In addition...

Time-resolved Particle Image Velocimetry of the flow in an acoustic standing wave tube

The flow field in an acoustic standing wave tube was measured using time-resolved particle image velocimetry (PIV). Verifications were made through comparisons between measured and predicted acoustic particle velocities in the spatial domain and the time domain. The accuracy of the time-resolved PIV system was satisfactory, at least for the periodic flow velocity component. The steady streaming...
