  • Residence Time Distribution in a rotor-stator spinning disc reactor
    2015
    Co-Authors: F. Visscher, M.h.j.m. De Croon, J. Van Der Schaaf, J.c. Schouten
    Abstract:

    This paper describes the Residence Time Distribution in a rotor-stator spinning disc reactor. This reactor consists of a disc with high rotation speed (up to 2000 rpm), between two stators with a small rotor-stator gap (0.5 to 3 mm). Residence Time Distribution experiments, at flow rates of 0.45 to 1.8 L/min, show that the flow in the rotor-stator spinning disc reactor can be described by a plug flow – mixer model. Predicted hydrodynamic velocity profiles confirm plug flow conditions in the center, and well mixed behavio

  • Residence Time Distribution in a single phase rotor stator spinning disk reactor
    Aiche Journal, 2013
    Co-Authors: F. Visscher, M.h.j.m. De Croon, J. Van Der Schaaf, Jos De Hullu, J Jaap C Schouten
    Abstract:

    A reactor model for the single-phase rotor–stator spinning disk reactor based on Residence Time Distribution measurements is described. For the experimental validation of the model, the axial clearance between the rotor and both stators is varied from 1.0 × 10−3 to 3.0 × 10−3 m, the rotational disk speed is varied from 50 to 2000 RPM, and the volumetric flow rate is varied from 7.5 × 10−6 to 22.5 × 10−6 m3 s−1. Tracer injection experiments show that the Residence Time Distribution can be described by a plug flow model in combination with 2–3 ideally stirred tanks-in-series. The resulting reactor model is explained with the effect of turbulence, the formation of Von Karman and Bodewadt boundary layers, and the effect of the volumetric flow rate. © 2013 American Institute of Chemical Engineers AIChE J, 59: 2686–2693, 2013

  • In-line measurement of Residence Time Distribution in a co-rotating twin-screw extruder
    Food Research International, 2003
    Co-Authors: F. Apruzzese, Stephen T. Balke, Janos Pato, Levente L. Diosady
    Abstract:

    The Residence Time Distribution in an intermeshing, co-rotating twin-screw extruder was measured in-line and off-line by stimulus-response technique. FD&C Red 40 was used as the tracer for the study. The die concentration was monitored in-line using a fiber-optic equipped vis-near Infrared spectrometer while the color concentration in the off-line samples was measured using a charge coupled device (CCD) spectrometer. The in-line results correlated well with the off-line method. The effect of feed rate, water content and temperature on the Residence Time Distribution were precisely determined and fit by the tanks in series (TIS) model. © 2003 Elsevier Science Ltd.
