Abstract Multiple radioactive particle tracking is a noninvasive technique used to study flow phenomena within gas‐solid fluidized beds. Five tagged polyethylene particles were added to a fluidized bed and tracked using two gamma cameras set perpendicular to one another. One camera collected x ‐ z particle locations and the other collected y ‐ z particle locations, while both cameras collected particle count rate values. The x ‐ z and y ‐ z particle movement information was combined to form three‐dimensional particle trajectories, and in turn used to calculate instantaneous flow information. The information from the five particles was then averaged and used to calculate three‐dimensional information regarding solid circulation parameters.
