Simultaneous measurement of bubble size, velocity and void fraction in two-phase bubbly flows with time-resolved X-ray imaging

Key parameters of two‐phase flows, such as void fraction and microscale bubble size, shape and velocity, were simultaneously measured using time‐resolved X‐ray imaging. X‐ray phase‐contrast imaging was employed to obtain those parameters on microbubbles. The void fraction was estimated from X‐ray ab...
