IGNITION OF HYDRAULIC FLUIDS IN HIGH PRESSURE PIPE SYSTEMS.
PENNSYLVANIA STATE UNIV UNIVERSITY PARK
Research was continued on a study of physical processes which govern the ignition, by rapid compression, of hydraulic fluids. Maximum gas temperature calculations were completed for the 38 inch I. D. test section. The results of these calculations are shown. Combustion tests were completed in the 78 inch I. D. test section for Cellulube 220 and Houghton-Safe 1055, and in the 38 inch I. D. test section for these fluids and Mil 2190 TEP. Combustion tests were com pleted in the 78 inch I. D. test section for the series of napthanic neutral oils with flash points varying from 300 to 500 F. The results indicate that the variation in flash point had no significant effect on the combustion limit curve. An analysis was made in order to deter mine the maximum pressures attainablee event combustion does occur in the case of the liquid charging study.
