Abstract

Observed data are presented to demonstrate the wide experimental possibilities opened by a method for visualizing a gas–liquid medium in fixed and fluidized granular beds by immersion tomography. The immersion tomography method stems from the fact that, by selecting the properties of an immersion liquid in a particular way, it is possible to keep the medium optically transparent (by varying dimensionless hydrodynamic and heat- and mass-transfer parameters) and also to reconstruct a three-dimensional image of the granular bed. The method was used to study the free rise of single gas bubbles in a fixed granular bed formed by glass beads 7 mm in diameter.
