Dimensionless quantities, such as p, e, and f are used in mathematics, engineering, physics,
and chemistry. In recent years the dimensionless groups, as demonstrated in detail here …

This study evaluates six turbulence models for mechanical agitation of non-Newtonian fluids
in a lab-scale anaerobic digestion tank with a pitched blade turbine (PBT) impeller. The …

Wear reduces velocity and turbulence by reducing the volume of impeller blades; yet there is
a lack of knowledge on flotation cells. Additionally, there is a lack of knowledge in the …

The development of new biopharmaceuticals relies on robust scale-up from small-scale
screening studies to industrial bioreactors. Novel SUB designs can prove highly beneficial …

Anaerobic digester is the most widespread technology for the treatment of biomass to
produce biogas. Mixing is an important parameter to have a highly efficient anaerobic …

A three-dimensional CFD model was developed in this work to simulate hydrodynamic
characteristics of a gas–liquid two-phase stirred tank with two six-bladed turbines and four …

Mixing of non-Newtonian fluids is widely encountered in the process industries. In this
research, we obtained a constitutive expression that relates the viscosity of a mixture of …

While mixing is considered critical in membrane distillation crystallisation, an explicit link
between mixing and crystallisation mechanisms has yet to be made. This study therefore …

In the present study, the effect of different kinds of impellers with different baffles or no baffle
was investigated. Up-pumping pitched blade turbine (PBTU) and Rushton turbine (RT) were …

A synthetic quaternary gas mixture (Methane= 85.24%, Ethane= 10.03%, n-Hexane= 0.02
mol%, Carbon dioxide= 2.49% and Nitrogen= 2.22%) has been used to study the effect of …
