I. Iliuta et al., HYDRODYNAMIC CHARACTERISTICS OF 2-PHASE FLOW-THROUGH FIXED-BEDS - AIRNEWTONIAN AND NON-NEWTONIAN LIQUIDS/, Chemical Engineering Science, 51(22), 1996, pp. 4987-4995
An experimental investigation was carried out to determine the effects
of gas and liquid how rates and flow consistency index on the liquid-
phase axial dispersion coefficient, pressure drop and the liquid holdu
p for two-phase downflow and upflow in a fixed bed. Water and non-Newt
onian liquids were employed as liquid phase. The liquid-phase flow in
a fixed bed was examined using the piston-diffusion-exchange (PDE) mod
el. The time-domain analysis of tracer response data was used for the
how model parameter estimation. Copyright (C) 1996 Published by Elsevi
