Flow regime transition and mass transfer intensification of microbubbles in graded fixed‐bed: Experiments and modeling

Abstract Particle size gradation in fixed‐bed reactors has been extensively studied, but almost exclusively with millimeter‐scale inlet bubbles. Whether these principles hold for sub‐millimeter (microbubble) scale, comparable to or smaller than the bed pore size, remains unclear....
