The objective of this investigation is to convert our "learning gas-solid-liquid"
fluidization model into a predictive design model. The IIT hydrodynamic model computes
the phase velocities and the volume fractions of gas, liquid and particulate phases. Model
verification involves a comparison of these computed velocities and volume fractions to
After a discussion of our research with the DOE-Air Products team in January, we
decided to concentrate on the slurry configuration of interest to DOE-Air Products which
has no recirculation of liquid. In such a system the gas is the continuous phase, rathd than,
the liquid that we had used in our model in the past. We have built such a cold fl2W twQ c-
dimensional plastic model. We have also changed our computer code. At the re ?est T
Air Products and DOE we have started a simulation of LaPorte RUN E-8.1 (1 1) fbr o-'
production of methanol as described in the Air Products report sent to us. For is61hernal n
operation, there is good mixing, and the preliminary results shown in this repordindiate ' -c

report will be prepared upon completion of the simulation. ' c--
Diana Matonis, a Ph.D. candidate supported by an IITRI fellowship, has*developed
a three dimensional version of our G-L-S code which will be used in the present study.
