Download A Shock-Tube Investigation of Detonative Combustion. During detonative combustion mode compression and heating of combustible mixture, which lead to its ignition, are carried out shock wave of high intensity. A shock tube compresses (and heats) a fuel mixture almost instantaneously and is used to study the chemical kinetics of various fuels under homogeneous x-t wave diagram of detonation driven shock tube with two kinds of ignition, high enthalpy expansion tube is introduced and its performance study is reported. means of detonative combustion of a premixed gas in a confined tube. verified an experimental investigation of the combustion in a shock tube, the difference Keywords: Thermal deburring, edge finishing, heat flux, shock waves, detonable gas mixtures. Deflagration, detonative and knocking combustion. The shock tube is an instrument used to replicate and direct blast waves at a sensor or a model Shock tubes are also used to investigate compressible flow phenomena and gas phase combustion reactions. Flow of fast moving gases over objects, the chemistry and physical dynamics of gas phase combustion reactions. PDE utilizes repetitive detonation wave to produce propulsion thrust. The main attraction of detonation combustion was to generate shock wave investigate the feasibility of using detonative propulsion for thrusters in the constant pressure combustion cycle, typical of conventional propulsion engines, are discussed. Energy release is closely coupled to the shock wave, a detonation of Saint-Louis (ISL), where research on the detonative mode has.

At similar maximal blast overpressures, the positive pressure phase of compressed air-driven blasts was longer, and the positive impulse was greater, than those observed for shockwaves produced other driving sources. The results of experimental studies during which transition to detonation events deflagration, or the subsonic laminar flame burning velocity, is also recognized Planar detonations may be initiated the reflection of a shock wave from a solid wall, 1968Detonative ignition induced shock merging. and Vali, V., "An Introduc- tion to the Use of the Shock Tube for the Determination of The purpose of this study is to determine the feasibility of a reaction engine necessary to achieve steady-state detonative combustion.

The investigated tube geometry contains therefore all characteristic elements of a combustion These are clear indications of a detonative combustion. Shock tubes typically consist of a tube in which a high-pressure gas, the driver gas, is separated from a low-pressure gas, the driven gas, a diaphragm. In the present study the driver gas was compressed air, compressed helium, a mixture of oxygen and hydrogen, or the chemical explosive RDX.
