IGNITION OF HYDRAULIC FLUIDS IN HIGH PRESSURE PIPE SYSTEMS
PENNSYLVANIA STATE UNIV UNIVERSITY PARK
Research was continued on a study of the physical processes which govern the ignition, by rapid compression, of hydraulic fluids. Maximum gas temperature calculations were completed for the 78 inch I.D. test section. The results of these calculations are shown. Combustion tests were completed for Cetane and Mil 2190 TEP in the 78 inch I.D. test section. Two methods of fuel introduction were used, microfog and a wick saturated with the test fluid. The results of these tests are summarized. The combustion test modifications were completed for the 38 inch and 1 12 inch I.D. test sections. An analysis for the case where the charging process is governed only by entrance and throttling losses was made for the liquid charging case. Expressions for predicting the pressure vs. time curve and the maximum pressure rise rate were derived and show good agreement with test results.
