Book Synopsis An Experimental Investigation of Longitudinal Combustion Pressure Oscillations by : J. R. OSBORN
Download or read book An Experimental Investigation of Longitudinal Combustion Pressure Oscillations written by J. R. OSBORN and published by . This book was released on 1962 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: The longitudinal mode of combustion pressure oscillations in a rocket moto was investigated. A premixed gaseous type rocket motor was utilized for this work. Experimental findings showed no change in oscillations when the heat transfer characteristics of the injector were varied. Any mechanism for longitudinal oscillations in a premixed gaseous rocket motor based on an oscillatory heat transfer to the injector is inadequate. (Author).

This book was released on 1962 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: Longitudinal combustion instability in a premixed gaseous propellant rocket motor was studied. The chamber length was varied continuously between 3 and 48 inches. A porous media injection plate was used to approximate uniform one-dimensional propellant injection. A showerhead injector was used to determine the influence of combustion zone recirculation on combustion instability. Two propellant combinations were used, methane (40% O + 60% N) and H - air. Results, in the form of instability maps, are presented for combination of the propellants and injection schemes. The two existing gas rocket instability driving mechanisms are presented and discussed. The influence of chemical kinetics on the instability seems to be unimportant and the driving mechanism is an oscillating heat transfer to the injector couples with a pressure oscillation in the combustion chamber to produce unstable combustion.

This book was released on 1985 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation of the mechanisms involved in combustion pressure oscillations in bypass flow configured solid fuel ramjets was conducted. Testing was done using cylindrically perforated polymethylmethacrylate fuel grains in solid fuel ramjet with 180 deg opposed dumps into a plenum ahead of an axial dump combustor inlet. Bypass flow into the aft mixing chamber was accomplished using two dumps located either 180 deg or 90 deg apart, perpendicular to the centerline. Split inlet feed line lengths into the plenum were varied with no apparent change of the dominant pressure oscillation frequency of approximately 167 Hz for bypass tests. Hot wire measurements indicated that in the short-coupled axial inlet, there were no dominant vortex shedding frequencies in the separation/shear layer or at the reattachment point on the fuel grain wall. The observed pressure oscillation frequency did not appear to be related to vortex shedding from the inlet jet. Coupling of the driving disturbance from bypass flow could possibly be with a longitudinal mode of the combustor or a Helmholtz mode involving the head section plenum. (Author).
