In the paper, the analysis of the chosen parameters effects (gas flow rate, the impeller speed, type of impeller and concentration of the aqueous solutions of sucrose) on the gas hold-up for gas-liquid and gas-liquid-biophase systems mechanically agitated are presented. Experimental studies were conducted in a vessel of the diameter of 0.288 m. The agitated vessel was equipped with Rushton or A 315 impeller. The results were described mathematically. The study shows that gas hold-up strongly depends on the impeller speed and the gas flow rate.

Badania miały na celu określenie wpływu wybranych parametrów (natężenia przepływu gazu, częstości obrotów mieszadła, typu mieszadła oraz stężenia wodnych roztworów sacharozy) na udział gazu zatrzymanego w cieczy dla mieszanego mechanicznie układu ciecz-gaz lub ciecz-gaz-biofaza. Badania wykonano w mieszalniku o średnicy D = 0,288 m, w którym na wale zamontowane było mieszadło turbinowe Ruszona lub A 315. Wyniki badań opracowano w postaci równia (1). Na podstawie przeprowadzonych pomiarów stwierdzono, że udział gazu zatrzymanego w cieczy silnie zależy od częstości obrotów mieszadła oraz natężenia przepływu gazu.
