Abstract: The influence of the agitator type, agitator speed, superficial gas velocity, type of sugar (glucose or sucrose) and the presence of yeast in the system on the gas hold-up in an agitated vessel with 24 vertical tubular baffles (located on the circuit in the vessel) has been presented in this paper. The measurement of gas hold-up was conducted in an agitated vessel with inner diameter of D = 0.288 m and liquid height of H = 0.288 m. Three different agitators were used in the experimental study. Five gas-liquid and two biophase-gas-liquid systems were agitated in an agitated vessel. Air was used as gas. The influence of gas flow number, Weber number, the mass fraction of aqueous sugar solution ci, and mass fraction of yeast suspension ys for gas-liquid and biophase-gas-liquid systems on the gas hold-up ϕ was described mathematically. These equations do not have equivalents in the literature.
