Theoretical framework
The theory interprets bubble column fluid dynamics through a single relationship Ω between the drift flux and the gas holdup, whose analytical form is built upon the flow regime transition points.
task#A.1
Analytical formulation of the operating curve across mono-dispersed and poly-dispersed homogeneous regimes, transition regimes with and without coalescence-induced structures, and pseudo- and pure-heterogeneous regimes.
task#B.2
A variable-coefficient formulation of the Zuber–Findlay drift-flux model, linking each point of the Ω-curve to the corresponding regime’s global and local flow properties.
task#A.3
Computation of the interfacial area along the operating curve, from which the CO₂ mass transfer rate is derived through mass-transfer models.
