CFD simulation of CO2 absorption by water-based TiO2 nanoparticles in a high pressure stirred vessel

Abstract This work presents the modeling and simulation of CO2 capture by a water-based Titanium dioxide (TiO2) solid nanoparticle in a stirred high-pressure vessel at a constant temperature. Photocatalytic material such as TiO2 has excellent properties, namely it is nontoxic, inexpensive, and non-p...
