Abstract
In this study, our purpose is to obtain instantaneous and mean velocity profiles in a Taylor-Couette vortex flow(TVF) by using a pulser receiver device based on a ultrasonic generator. The experiment was carried out with a small aspect ratio where the Ekman boundary layer was not neglected. The device has a radial ratio of 0.375,aspect ratio of 3 and the gap length between the inner and outer cylinders of 25. As the result, the velocity profiles and their absolute values were in good agreement with the ones obtained by the Ultrasonic velocity profiler (UVP), which results in well approximated in the vortex structures of Normal 2 and 4 cell modes. This measurement system was applied to the multi-phased flow as a solid-liquid flow experimentally, and well measured even in the dilute solution up to 2.0g/400ml.
