HIGH PRESSURE IGNITION.
Abstract
Research was continued on a study of the physi cal processes which govern the ignition, by rapid compression, of hydraulic fluids. The 7/8 inch I.D. test section was modified to allow testing of a fog of fluid having droplets with a diameter less than 10 microns. Testing was in this apparatus using Cetane as a test fluid. While these tests have not yet been completed, the initial indications are that the fog will ignite at pressure rise rates slightly lower than those for which the wick will ignite, for a given final pressure. Calculations have begun to determine the maximum temperatures attained in the driven gas for a variety of pressure rise rates and final pressures. The liquid charging test apparatus was modified in order to study the throttling effects in terms of the size of an orifice inserted immediately upstream of the valve. A series of tests was run using the modified apparatus. (Also see AD-417 599 to 417 607 and AD-417 609 to 417 614). (Author)
