HIGH PRESSURE IGNITION.
Abstract
Research was continued on a study of the physical processes which govern the ignition, by rapid compressions, of hydraulic fluids. Preliminary combustion tests were run using Cetane as a test fluid. The general results of these tests are given. A convection correlation was de veloped for combined free and forced convection in a horizontal tube that suits the analysis employed to determine gas temperatures in the downstream pipe. Construction of the liquid charging apparatus was completed. Preliminary tests, using water as a charging fluid, were run to investigate the nature of the pressure vs. time curve for a rapidly compressed column of air. All of the curves obtained wmped oscillatory in nature with extremely high pres sure rise rates and maximum pressures indicated to be far above the driving pressure. Two prob lem areas arise: (1) Compression ignition; (2) Structural damage to a piping system due to extreme pressures. (Also see AD 417 599 to 417 605 and AD 417 607 to 417 614. (Author)
