WebA new method based on ultra-fast X-ray imaging was developed in this work for the investigation of the dynamics and the structures of complex two-phase flows. In this paper, cavitation was created inside a millimetric 2D Venturi-type test section … In the present work, X-ray measurements were based upon two different mechanisms: absorption and phase-contrast enhancement. Commonly employed in numerous studies of two-phase flows using X-rays, absorption allows to obtain flow structures by means of energy attenuation. In fact, when an X-ray travels … See more The X-ray imaging technique of the APS Synchrotron has been utilised in a previous work by Im et al. (2007) for velocity measurements in a single-phase flow with a very low speed (80 \upmum/s), which required low … See more The quality of velocity measurements relies considerably on the characteristics of the tracers used during the experiments, which is all the more true in the case of two-phase flows given that particle detection is … See more
