Physical and numerical characterisation of an agitated tubular reactor (ATR) for intensification of chemical processes

• Dynamics of driven ATR characterised experimentally and numerically. Optical acoustic methods agree well with LBM numerical model. Mixing regime depends strongly on applied amplitude, a , agitation frequency, f . power number increases re as 2 3 above critical value. Agitator tube induces fluid wakes, motion closely coupled to velocity field. This study investigates the dynamics novel, oscillatory, intensified plug-flow reactor – an agitated tubular (ATR) designed for efficient flow processing solid-liquid mixtures. The relative movement agitator bar, associated effects mixing, were physically suite experimental instruments utilising laser-based, video-based techniques numerically via Lattice Boltzmann method (LBM) computational dynamic simulation. volume consisted cylindrical outer containing free-moving, perforated tube. position, angular inner measured computationally under range realistic operating conditions, in terms frequency displacement distance, along their effect turbulence levels. Additionally, simulations used validate model input. agreement between simulation data was very good all cases, leading clear recommendations optimal while derived map types magnitudes is also presented.
