ABSTRACT:
A new non-intrusive method for measuring the throughflow velocity crossing the
dome of erupting bubbles in freely bubbling 2-D fluidized beds is presented. Using a
high speed video-camera, the dome acceleration, drag force and throughflow
velocity profiles are obtained for different experiments, varying the superficial gas
velocity. The acceleration profiles show greater values in the dome zone where the
gravity component is negligible. The drag force and the throughflow velocity profiles
show a uniform value in the central region of the dome (40 deg < < 140 deg) and
the total throughflow increases with the superficial gas velocity.
