CFD predicted pH gradients in lactic acid bacteria cultivations
The formation of pH gradients in a 700 L batch fermentation of Streptococcus thermophilus was studied using multi‐position pH measurements and computational fluid dynamics (CFD) modeling. To this end, a dynamic, kinetic model of S.

Sustainable Thermal Solutions: Enhancing Heat Transfer with Turbulators and Nanofluids
Nanofluids, which are nanoparticle suspensions in base fluid, facilitate heat transmission due to their improved thermal conductivity. Turbulators, which are inserts into fluid flow channels, disturb the flow, increasing turbulence and hence the heat transfer rate.

Scaling‐down biopharmaceutical production processes via a single multi‐compartment bioreactor (SMCB)
Abstract Biopharmaceutical production processes often use mammalian cells in bioreactors larger than 10,000 L, where gradients of shear stress, substrate, dissolved oxygen and carbon dioxide, and pH are likely to occur. As former tissue cells, producer cell lines such as Chinese hamster ovary (CHO) cells sensitively respond to these mixing ...

A computational fluid dynamic study is conducted to investigate the effects of using porous carbon inserts (PCIs) on water management and the performance of proton exchange membrane fuel cells. The results show that employing PCI leads to a more efficient water removal from the fuel cell and higher oxygen transport throughout the cell, which ...
