Grid Independence Study and a Finite Difference Collocation Approach for Magnetized CeO2‐Ti3C2/H2O Hybrid Nanofluid Flow Over an Inclined Spinning Disk With Newtonian Heating

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This work examines magnetohydrodynamic (CeO2, Ti3C2/H2O) hybrid nanofluid (HNF) flow on an inclined revolving disk with effects of Newtonian heating. HNF is obtained by suspending the nanoparticles (NPs) of CeO2 and Ti3C2 in water (H2O). The flow is affected by mixed convection, Joule heating, nonlinear thermally radiative and dissipative ...

Impact of Agitation Power Input on Aspergillus oryzae Metabolism: Application of Multi‐Omics on an Industrial Enzyme Fermentation

Biotechnology and Bioengineering, EarlyView.
ABSTRACT The agitation power input substantially impacts the oxygen transfer rate in aerobic fermentation processes. Furthermore, in a carbon‐limited process where the substrate feed rate is controlled by the concentration of dissolved oxygen, the power input will consequently govern the feed rate.

Comparative Analysis of Bioreactor Design and Scale‐Up for Cultivated Meat Using Monte Carlo‐Based Timescale Modeling

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Cultivated meat offers a sustainable alternative to conventional livestock production but faces significant scale‐up challenges, particularly in bioreactor design for mammalian cell suspension cultures. This study presents a comparative analysis of stirred tank reactors (STR), bubble columns (BC), and airlift reactors (ALR) to assess their ...
