The agitated vessel with internal diameters of T = 0:288 m and T = 0:634 m was filled with a liquid up to the height H = T. For the purpose of measurements, two high-speed impellers were used: Rushton turbine impeller (RT) or A 315 impeller.Within the study, the following parameters were altered: superficial gas velocity, impeller speed, impeller type and concentration of aqueous sucrose solution. In addition, influence of the vessel scale on gas hold-up value was analysed. Experimental results were mathematically described. Equations (5)–(7) do not have equivalents in the literature.}, type={Article}, title={The effect of vessel scale on gas hold-up in gas-liquid systems}, URL={http://www.czasopisma.pan.pl/Content/118937/PDF/art01.pdf}, doi={10.24425/cpe.2020.136010}, keywords={agitated vessel, mixing, gas hold-up, aqueous sucrose solution}, }
