Abstract
This paper describes the measurement of particle behavior inside a spouted bed by using MRI. We measured the particle velocity distribution in the annulus region in a three-dimensional cylindrical spouted bed. The tagging method and the phase method, which are the velocity measurement technique of MRI, are employed to measure the particle velocity distribution. A stagnation region near the corner of the vessel is clearly visualized by the tagging method. A plug-like motion of particles in the upper part is also visualized. The velocity distribution obtained by the phase method is integrated to calculate particle flow rates at each height.
