Gas dispersion in non-Newtonian fluids is encountered in a broad range of chemical,
biochemical, and food industries. Mechanically agitated vessels are commonly employed in …

The efficiency of dark fermentation, as one of the most promising bioconversion
technologies to produce biohydrogen, largely depends on some important parameters, such …

In this work, we present the results collected in a gas-liquid stirred tank by a combination of
experimental and computational methods, with the aim of presenting original data on the …

Aerated mixing operations rely on the efficient distribution of the gas phase throughout the
liquid, which is particularly important for many industrial processes. In this regard, coaxial …

Gas dispersion in non-Newtonian fluids has numerous applications in many chemical and
biochemical applications. However, the effect of the power-law model constants describing …

The effective removal of gas phase species relies on effective gas liquid hydrodynamic
contact coupling with fast chemical reaction rates. To promote mass transfer rate and the …

Computational fluid dynamics (CFD) is a widely used tool for investigating fluid flows in
bioreactors. It has been used in the biopharmaceutical industry for years and has …

One of the significant challenges in the efficient operation of bioreactors is uniform gas
dispersion in very viscous non-Newtonian fluids because of the complex rheology exhibited …

To reduce the power consumption and improve the mixing performance in stirred tanks, two
improved disc turbines namely swept-back parabolic disc turbine (SPDT) and staggered fan …

Organisms used in fermentation processes are sometimes inhibited by accumulation of
products or by-products. One route to circumvent this is via extractive fermentation. To …
