Full flow field computation of mixing in baffled stirred vessels

Abstract

The ability to numerically simulate the whole flow field in stirred vessels is fast becoming vital to their optimal design. Past attempts have adopted a steady-state, semi-empirical analysis requiring experimentally-based input in some form. A numerical method is developed for the computation of the full time-varying flow field for both the fluid within the impeller passages and that outside. Results of calculations are compared with experimental data for a model stirred vessel
