“…Bin et al 7 investigated major hydrodynamic parameters such as gas hold-up, phase velocities and axial dispersion. Son et al 8 investigated and diagnosed bubble chord length, frequency and hold-up using a dual electrical resistivity probe system in a counter-current bubble column bioreactor. Li et al 9 applied hotfilm anemometry to measure the gas hold-up in a counter-current bubble column and to analyse the gas hold-up distribution across different sections of the column.…”

BACKGROUND: In order to improve the performance of a counter-current bubble column, radial variations of the gas hold-ups and mean hold-ups were investigated in a 0.160 m i.d. bubble column using electrical resistance tomography with two axial locations (Plane 1 and Plane 2). In all experiments the liquid phase was tap water and the gas phase air. The superficial gas velocity was varied from 0.02 to 0.25 m s −1 , and the liquid velocity varied from 0 to 0.01 m s −1 . The effect of liquid velocity on the distribution of mean hold-ups and radial gas hold-ups is discussed.

“…5(b)). Since the correlation dimension is a measure of the spatial homogeneity in the phase space, the increment of D C means that the underlying system becomes non-homogeneous and more complicated and chaotic [18][19][20]. It is anticipated from these that the predictability of hydrodynamic phenomena diminishes in the slurry bubble column with increasing U G , owing to a great deal of complex information.…”

The hydrodynamics and heat transfer characteristics were investigated in a slurry bubble column reactor whose diameter was 0.0508 m (ID) and 1.5 m in height. Effects of gas velocity (0.025-0.1 m/s), pressure (0.1-0.7 MPa), solid concentration (0-20 vol%) and liquid viscosity (1.0-38.0 mPa s) on the hydrodynamics and heat transfer characteristics were examined. The pressure difference fluctuations were analyzed by means of attractor trajectories and correlation dimension to characterize the hydrodynamic behavior in the column. The gas holdup increased with increasing gas velocity or pressure, but decreased with increasing solid concentration or liquid viscosity. It was found that the attractor trajectories and correlation dimension of pressure fluctuations were effective tools to describe the hydrodynamic behaviors in the slurry bubble column. The heat transfer coefficient increased with increasing pressure or gas velocity, but decreased with increasing solid concentration or viscosity of slurry phase in the slurry bubble column. The heat transfer coefficient value was well correlated in terms of operating variables and correlation dimension of pressure fluctuations in the slurry bubble column.
