Numerical study of glare spot phase Doppler anemometry

Superimposed Non Interfering Probes to extend the Phase Doppler Anemometry size range

In classical phase Doppler systems three detectors are commonly used to determine the particles size whatever, basically, this technique requires only two detectors. The third detector is in fact mainly used to overcome the 2 ambiguity on phase-shift measurements. In the present work an alternative solution is introduced which allows to keep the same accuracy and dynamic range of the size measu...

Using Phase Doppler Anemometry and High Speed Imaging to Analyze MDI Spray Plume Dynamics

Laser Doppler anemometry: recent developments and future challenges

The availability of new optical and electronic components and the increasing demands on measurement accuracy have led to a continuous development of the laser Doppler measurement technique in recent years. This article reviews the developments in optical systems, signal processing, data processing and in the application of LDA systems. Particular emphasis is placed on examining how well present...

Laser Doppler Anemometry Study of the Flow in a Blood Filter

Damage to red blood cells can be induced chemically, by osmosis or mechanically. The fluid mechanical effect can be related to the device design, its surface characteristics and to the degree of flow disturbance or turbulence caused by the device. Is generally accepted that the presence of high turbulent shear stresses generated in the flow fields of artificial devices are partially responsible...
