During the past quarter, research efforts have concentrated on investigating the droplets effects on particulates, smoke, and NO/sub x/ emissions using the variable spray momentum injector under normal excess air and staged combustion conditions. A total of four fuels have been tested, including an SRC-II blend with middle and heavy distillate. Test results indicated that within the range of droplet sizes and injection velocities investigated, particulate emissions are not strongly dependent upon droplet parameters. The greatest effect was observed for relatively large droplets (500 ..mu..m) in regions of low slip velocity. The flame studies research effort was concentrated upon the completion of the droplet experiments. Features observed include microexplosions of individual droplets, oil-coke cenosphere formation for residual fuel oil, and violent secondary atomization of droplets blended from heptane and heavy synthetic fuel oil. At fuel-rich conditions, droplet soot was correlated with carbon/hydrogen ratio for a number of fuels. Further work focused on the coupling between the thermal and chemical processes within the soot formation region, on the morphology of the soot, and on visualization of individual droplet combustion.
