Hydrodynamics, oxygen transfer, and oxygen uptake in bubble-column and airlift bioreactors
were studied using multiphase Euler-Euler computational fluid dynamics (CFD) simulations …

In many biological processes, increasing the rate of transport of a limiting nutrient can
enhance the rate of product formation. In aerobic fermentation systems, the rate of oxygen …

A full‐scale, closed‐loop bioreactor (Orbal oxidation ditch, Envirex brand technologies,
Siemens, Waukesha, Wisconsin), previously examined for simultaneous biological nutrient …

In this study, a lab-scale continuous packed-bed bioreactor with multi-sized distributed
particles has been simulated in a structured layout using computational fluid dynamics. The …

For dynamic behaviors of continuous airlift bioreactors, a mathematical model based on a
tanks-in-series model with backflow has been developed. The equations describing the …

In an effort to optimize the economy and performance of covered anaerobic reactor systems,
a comprehensive dynamic and mechanistic model was created to simulate the constituent …

A full-scale closed loop bioreactors (Orbal™ oxidation ditch) previously examined for
simultaneous biological nutrient removal (SBNR) was further evaluated using computational …

Industrial aerobic fermentation processes are performed in large-scale bioreactors (> 20 m
3). Understanding the local values of the velocity field, the eddy dissipation rate and the gas …

Airlift reactors have been used widely in many industrial processes, but little work has been
conducted on such reactors integrated with internals. In this study, a novel airlift reactor with …

We report the findings of a detailed assessment of various options for computational two-
fluid RANS simulations of an aerated agitated 2-L bioreactor equipped with a single baffle …
