Residence time distribution (RTD) profiles were investigated in a standard oscillatory baffled reactor (OBR) as a function of oscillatory and bulk flow components using a design of experiments (DoE) approach. A second-order, polynomial model (R-2 = 92.1%) was fitted to N values estimated from concentration profiles and used to maximise plug flow conditions. The velocity ratio (Psi) required to maximise plug flow was 1.9, agreeing well with the range previously identified by Stonestreet and van der Veeken (1.8 < Psi < 2.0), suggesting that the approach used here is valid. This method could be used to rapidly quantify and maximise plug flow in various OBR designs in a simple and robust manner which could prove valuable for the operation and design of continuous processes using OBR technology.
