Download or read book An Experimental Investigation of the Supersonic Combustion of Vitiated Air-hydrogen Mixtures written by R. E. Davis and published by . This book was released on 1970 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests were conducted utilizing an arc heater as a high enthalpy air source to determine the effects of water vapor contamination on a hydrogen-air supersonic combustion process. A flow apparatus was constructed to permit vitiated, arc-heated airflow to mix coaxially with hydrogen in a constant area duct. The hydrogen was injected at the exit of the vitiated air nozzle which was designed for M = 2.8. Data were obtained in the form of wall pressure distributions and impact pressures and gas samples obtained from nonquenching pitot probes. The enthalpy of the mixture was varied from 1360 to 1860 Btu/1bm and the water vapor mass percent in the vitiated air was varied from 0 to 23. (Author).
