FULL FLOW-FIELD COMPUTATION OF MIXING IN BAFFLED STIRRED VESSELS

The ability to numerically simulate the whole flow field in stirred ve ssels is fast becoming vital to their optimal design. Past attempts ha ve adopted a steady-state, semi-empirical analysis requiring experimen tally-based input in some form. In the present work, a numerical metho d is developed for the computation of the full time-varying flow field for both the fluid within the impeller passages and that outside. Res ults of calculations are compared with experimental data for a model s tirred vessel.
