摘要

Ensemble averaged solids velocity fields in an interconnected Fluidized Bed reactor were constructed from the trajectory of a single radioactive particle measured with a Positron Emission Particle Tracking system. The tracking system can locate a particle inside the experimental setup with a 3D resolution below 15 mm for velocities of 1 m.s~(-1) and below 5mm for velocities of 0.1 m.s~(-1). Characteristic flow elements like orifice flow, weir passage, circulation vortices and bubble bursts can be visuallized well.
