Abstract

In this paper, we present the mass transfer during the buoyant CO 2 bubble absorption in a particle suspension by the experimental and computational studies. In the experimental study, the transient evolution of a single bubble behavior is visualized for the CO2 absorption in Al2O3-nanofluids. In the computational study, the finite element approximated Navier-Stokes equations are employed integrating with a level set method for tracking the interface on the convective diffused mass transfer in a CO2 bubble with the multi-freely suspended non-Brownian Al2O3-particles. In both approached studies, the particle hydrodynamic effect to the bubble motion takes effect on increasing the mass transfer area followed by inducing the mass transfer enhancement (MTE) by a term of the larger mass transfer coefficient (MTC) at the gas-liquid phase. From computational study, this is also supported that the enhanced mass flux is highly influenced by the particle hydrodynamics on the bubble surface in a buoyant bubble. Consequently, it can lead to find an existence as one of possible mechanisms for MTE on a gas-absorption in a suspension.
