Gas bubbles play an important role in the mechanics of fluidized beds, however, it is very challenging to obtain spatially and temporally resolved information about the hydrodynamics in gas solid fluidized beds. Pseudo-2D systems (Hele-Shaw cell) have been used to obtain real-time images. Due to their geometrical simplifications and wall effects, such pseudo-2D systems should be regarded as approximations. In this work we use real-time MRI to quantify the influence of wall effects on the fluidized hydrodynamics in gas solids fluidized beds.
