Theoretical framework<\/p>\n\n\n\n

The bubble column operating curve<\/h2>\n\n\n\n

The theory interprets bubble column fluid dynamics through a single relationship \u03a9 between the drift flux and the gas holdup, whose analytical form is built upon the flow regime transition points.<\/p>\n\n\n\n

task#A.1<\/p>\n\n\n\n

Regime taxonomy<\/h3>\n\n\n\n

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.<\/p>\n<\/div><\/div>\n<\/div>\n\n\n\n

Variable drift-flux model<\/h3>\n\n\n\n

A variable-coefficient formulation of the Zuber\u2013Findlay drift-flux model, linking each point of the \u03a9-curve to the corresponding regime’s global and local flow properties.<\/p>\n<\/div><\/div>\n<\/div>\n\n\n\n

task#A.3<\/p>\n\n\n\n

Mass transfer closure<\/h3>\n\n\n\n

Computation of the interfacial area along the operating curve, from which the CO\u2082 mass transfer rate is derived through mass-transfer models.<\/p>\n<\/div><\/div>\n<\/div>\n<\/div>\n<\/div><\/div>\n<\/div><\/div>\n\n\n\n
