A PBM-Based Procedure for the CFD Simulation of Gas–Liquid Mixing with Compact Inline Static Mixers in Pipelines

A compact static mixer for gas–liquid dispersion in pipelines is studied this paper with a Reynolds averaged two fluid model approach. procedure based on the lumped parameter solution of population balance applied to obtain bubble Sauter mean diameter needed interphase forces. The gas distribution pipe analyzed different operative conditions and efficiency assessed terms homogeneity section, low coefficients variations being obtained. computational volumetric mass transfer coefficient, kLa, developed partially segregated systems finding kLa values comparable those typically obtained other mixers. proposed allows us locally analyze oxygen rate by observing limitations due accumulation behind body mixer, which leads local depletion driving force. Geometrical optimization element proposed, analysis dynamics phenomena.
