This is the final report of a proposed three-year, Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). The project was terminated after the first year due to changes in funding priorities. The objective of the project was to develop a self-sustained research program for advanced computer simulation of industrial reactive multiphase flows. The prototype research problem was a three-phase alumina precipitator used in the Bayer process, a key step in aluminum refining. Accomplishments in the first year included the development of an improved reaction mechanism of the alumina precipitation growth process, the development of an efficient method for handling particle size distribution in multiphase flow simulation codes and finally the incorporation of precipitation growth and agglomeration kinetics in LANL`s CFDLIB multiphase flow code library
