Challenges of High Viscosity Mixing

16-2 VISCOUS MIXING FUNDAMENTALS 16-2.1 Challenges of High Viscosity Mixing 

Mixing is an operation whereby the nonuniformity within a mixture is reduced. Mixing in very viscous systems can be a formidable task. There are no turbulent

Heat transfer coefficients are also poor in very viscous systems, and the steps normally taken to improve heat transfer in cooling, such as increased agitator speed or greater temperature differences, can be counterproductive because of the heat generated from viscous energy dissipation.
