Summary
Mixing experiments are often essential for successful process development and scale-up. The techniques and equipment required to make both qualitative and quantitative measurements of mixing processes are discussed. Emphasis is placed on practical instructions on how to perform the techniques and analyse the resulting data. Examples of typical data are included. Guidance on why and when mixing experiments should be performed is provided, as is information on some of the essential equipment and model fluids required to perform a typical range of mixing experiments. Sections describing the different types of measurements follow. These include rheology measurement, power measurement, miscible liquid phase mixing or blend time, solid–liquid mixing, immiscible liquid–liquid dispersion and gas–liquid mixing and mass transfer. A final extensive section describes the direct flow measurements LDA (or LDV), PDA, and PIV from both theoretical and practical perspectives.
