The production rate of fed-batch aerobic fermenters is often limited by the oxygen transfer
rate that depends on the fluid dynamics of the gas-liquid system. In turn, ideal flow regimes …

The main features of the flow generated by three axial flow impellers installed on the side of
cylindrical tanks filled with pseudoplastic solutions exhibiting yield stress were exposed …

The commercial success of mammalian cell-derived recombinant proteins has fostered an
increase in demand for novel single-use bioreactor (SUB) systems that facilitate greater …

CFD simulations of mixing in single-phase multi-Rushton stirred tanks based on the RANS
methodology frequently show an over-prediction of the mixing time. This hints at an under …

This paper presents simulation of rotating impeller in a mixing vessel by means of
Computational Fluid Dynamics (CFD). A special emphasis is devoted to the study of …

The mixing of shear thinning fluids in a cylindrical vessel has been investigated in this paper
via numerical simulation. The agitation is ensured by a modified anchor impeller (MAI): it …

Hydrodynamics of gas-liquid flow in a round-bottom stirred tank is modelled at two gas flow
rates, constant bubble size and agitator speed of 300 rpm. A round-bottom tank equipped …

The flow generated in a gas-liquid stirred tank reactor highly depends on the design of the
impeller and sparger. To better understand the contact between the phases and the mass …

The hydrodynamics of stirred vessels with side-entering impellers, which are used in
numerous process industries including petroleum, foods, and pulp and paper …

The distribution of buoyant solid particles in agitated suspensions has been studied. The
investigation was carried out in a baffled vessel characterised by an aspect ratio equal to …
