Simulation of two‐phase air–liquid flows in a closed bioreactor loop: Numerical modeling, experiments, and verification

“…4,6 The experimental information about the flow structure, its averaged, and pulsation properties is essential both for computer analysis of the two-phase gas-liquid medium motion inside a large class of process devices and for controlling the state of two-phase flows that determine the hydrodynamic environment and mass transfer processes, in particular, in bioreactors. [17][18][19][20][21][22][23][24][25] The development of integro-differential models and using them to simulate complexly interacting carrier and dispersed phase is an urgent interdisciplinary task. The new models allow for a broader fundamental understanding and management of the hydrodynamic environment in bioreactor circuits [26][27][28][29][30] and can provide the basis for comprehensive systematic microbiological studies of the behavior of microorganisms in local apparatus, such as fermentation devices that implement aerobic biosynthesis processes.…”

“…The most modern methods of analysis and scaling of process solutions based on achievements of practical physics, chemistry, and biotechnology are based on computational fluid dynamics (CFD) tools 4,6 . The experimental information about the flow structure, its averaged, and pulsation properties is essential both for computer analysis of the two‐phase gas–liquid medium motion inside a large class of process devices and for controlling the state of two‐phase flows that determine the hydrodynamic environment and mass transfer processes, in particular, in bioreactors 17–25 .
