cfd hydrodynamics analysis of syngas flow in slurry bubble column
Authors
abstract
in this paper, a cfd model of syngas flow in slurry bubble column was developed. the model is based on an eulerian-eulerian approach and includes three phases: slurry of solid particles suspended in paraffin oil and syngas bubbles. numerical calculations carried out for catalyst particles, bubble coalescence and breakup included bubble-fluid drag force and interfacial area effects. also, the effects of solid particles existing in liquid phase were described.
