چکیده مقاله:
The mixing action in airlift bioreactors is caused by the motion of air bubbles inside the liquid. In this apparatus, the return flow of the liquid inside the reactor rotates in addition to the bubble inside the liquid moving, which aids in the mixing process more. Low shear stress, low operating costs, and excellent mass transfer are the three main benefits of airlift bioreactors. The program COMSOL version ۵ was used to model an airlift bioreactor with an external flow loop for this paper.The results showed that when the gas moved more in the reactor's core, its top-of-chute gas velocity decreased and as a result, the amount of liquid it carried back from the reactor decreased.
