Investigation of mass Transfer in Viscous Non-Newtonian Fluid in Bubble Column by means of CFD

In this research, the mass Transfer of oxygen from the gas phase to the non-Newtonian fluid containing three Carbopol aqueous solutions in a bubble column is investigated by means of the Computational Fluid Dynamic. The Herschel Bulkley model for estimating the rheological behavior of several non-Newtonian fluids was used. The results of simulation was compared with the experimental results and showed acceptable agreement.
