"Throughflow velocity crossing the dome of erupting bubbles in 2-D fluidized beds", in: Bi, X., Berruti, F., Pugsley, T., (Eds.), Fluidization XII, ECI, New York, p. 169-176.978-0-918902-57-3http://hdl.handle.net/10016/1221A 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 and the total throughflow increases with the superficial gas velocity.application/pdfengFluidized bedErupting bubbleThroughflowconference paperIngeniería IndustrialFísicaopen access
