Abstract

We report experimental flow pattern and associated residence time distribution measurements for multipass and multitube arrays where periodic baffles and fluid oscillation may be present. The observations show that controlled mixing and well-defined residence time distributions can be obtained for both the engineering configurations tested. In addition, a single parameter axial dispersion coefficient is determined and it is shown that dispersion using oscillatory flow in baffled tubes can be less than axial dispersion for a turbulent net flow.
