ABSTRACT:

During the first quarter of this research into circulation patterns in bubble column reactors a literature survey has been undertaken and has revealed new, relevant articles which are currently in review. The laboratory scale bubble column to be used in the experimental research has been designed and is under construction. Preliminary research using a small existing column has verified the use of resistance probes for measuring local gas void fraction in the column although overall voidage measured is a little low. Data from this column are presented to show that the distributor plate has an effect on circulation pattern. A one-dimensional model for circulation in non-Newtonian systems is presented. Research using laser doppler velocimetry and numerical fluids modeling will commence in the next quarter while probe research will continue. 10 refs., 51 figs. (ERA citation 13:032421)
