- Abstract
Recent developments in magnetic resonance (MR) imaging techniques give measurements of particle velocities and voidage fractions in a bubbling fluidized bed, with a spatial resolution of approximately 0.6 mm and a time resolution of approximately 2 ms. The particles contained liquid, whose mobile molecules have more favorable relaxation times (T1, T2 and T), than for solids, facilitating rapid MR measurements. Seeds 0.5–2 mm in diameter containing oil and hollow, plastic spheres 1–10 mm in diameter filled with water were used.
