Book excerpt: The work in this thesis is concerned with an investigation of the performance of a commercially available design of in-line motionless mixer and how this is affected by the major process variables. Much of the previously reported work on mixing studies has been based on empiricism, particularly that carried out on in-line mixers. Because of this it has been possible to identify several areas where an experimental and theoretical investigation would provide a useful and original contribution to the state of knowledge. The study has investigated the pressure drop and mixing characteristics of a Kenics in-line mixer, in laminar flow, using a range of Newtonian and non-Newtonian liquids. It has been shown that the pressure drop can be correlated by an equation of the Ergun type. A new mixing index, which aims to quantitatively express the goodness of mixing, has been determined over a wide range of operating conditions. This mixing index has been correlated with the major system variables using a number of mathematical techniques. A theoretical study of a twisted tape model has been carried out by tensor analysis techniques using a rotating helical co-ordinate system. A series of partial differential equations has been derived, which describe the behaviour of a fluid flowing through such a geometry.
