Work performed during the fourth quarter of the contract is described. The modification of the Baum-Levine rocket motor program for use in the pulsating coal gasification code was completed during this quarter. As part of this effort, several subroutines in the Baum-Levine program were modified, and new ones developed, for obtaining the gasifier boundary solutions. The testing of the various subroutines in the coal gasification code was also completed during this quarter. Parametric studies were initiated with the new code and some steady-state solutions were obtained. In addition to the theoretical effort, experimental studies were also performed to determine a suitable gasifier configuration for the experimental phase of this research program. Based on the results of these studies, and some literature search, a gasifier configuration was decided upon during this quarter. 6 refs., 14 figs., 2 tabs.
