On interrelations between the theory and experiments of macromixing in stirred tanks

Measures of mixture homogeneity and their links with mixing time measuremen ts were discussed, The statistical foundations of homogeneity measures for different scales of scrutiny were presented, followed by the differential m ixing model application to defining conditions of physical similarity for m acromixing. Selected variable effects on mixing time were studied by means of the CFD analysis. The conclusions drawn from this study can help underst and importance of some process parameters. Reasons for a broader discussion on standard experimental procedures were also specified.
