Tackling Difficult Mixing Problems - AIChE

Tackling Difficult Mixing Problems - AIChE

Mixing non-Newtonian fluids may be doubly complicated when the mixing process creates the non-Newtonian proper-ties. For example, a formulation process may start with a low-viscosity liquid, and mixing causes the viscosity to increase until the fluid becomes non-Newtonian. Sometimes mixer power may be used as an indicator of final fluid viscosity.

LIQUID-LIQUID MIXING IN STIRRED VESSELS: A REVIEW .

LIQUID-LIQUID MIXING IN STIRRED VESSELS: A REVIEW .

Liquid-liquid mixing is a key process in industries that is commonly accomplished in mechanical agitation systems. Liquid-liquid mixing performance in a stirred tank can be evaluated by various parameters, namely minimum agitation speed, mixing time, circulation time, power consumption, drop size distribution, breakup and coalescence, interfacial area, and phase inversion.

Batch Reactor - an overview | ScienceDirect Topics

Batch reactors can be operated as static or mixed; a T-flask is static (Fig. 3.1) and a stirrer flask, such as a Techne® Flask (Fig. 3.2) is mixed. Mixing helps remove concentration gradients and provides shear. Static batch are poorly mixed, do not induce shear, and rely on diffusion for mass transfer.
