Detonation driver for enhancing shock tube performance
نویسندگان
چکیده
The development of a shock-induced detonation driver for enhancing the performance of a shock tube is described. The detonation wave is induced by the expansion of helium or air. Various gaseous fuel–oxidizer combinations are examined. This method produces a detonation wave which propagates downstream that transitions into a shock wave in the driven section. High-enthalpy flows with a maximum total temperature of 4200K and a maximum total pressure of 34 atm in the driven tube are achieved. The problems of achieving the so-called perfectly-driven mode as well as those of inadequate fuel–oxidizer mixing are discussed.

Detonation Initiation via Imploding Shock Waves
An imploding annular shock wave driven by a jet of air was used to initiate detonations inside a 76 mm diameter tube. The tube was filled with a test gas composed of either stoichiometric ethylene-oxygen or propane-oxygen diluted with nitrogen. The strength of the imploding shock wave and the sensitivity of the test gas were varied in an effort to find the minimum shock strength required for de...

Weperformexperimental andnumerical studies of a shock tubewith an open end.The purpose is to investigate the impulse due to the exhaust of gases through the open end of the tube as amodel for a partially filled detonation tube as used in pulse detonation engine testing.We study the effects of the pressure ratio (varied from3 to 9.2) and the volume ratio (expressed as fill fractions) between the...
متن کاملDetonation Initiation in a Tube via Imploding Toroidal Shock Waves
The effectiveness of imploding waves at detonation initiation of stoichiometric ethyleneand propane–oxygen– nitrogen mixtures in a tube was investigated. Implosions were driven by twice-shocked gas located at the end of a shock tube, and wave strength was varied to determine the critical conditions necessary for initiation as a function of diluent concentration for each fuel. Hydrocarbon–air mi...
متن کاملDetermining Shock and Detonation Wave PropagationTime Using Wavelet Methods
The propagation speed of a shock or detonation wave in a shock or detonation tube is usually determined by a time-of-flight method by dividing the distance between two transducers with the propagation time of the disturbance signal. Some arbitrariness is inherent in determining the propagation time by this method. A new method based on Haar and Morlet wavelet transforms is reported. The method ...
متن کاملExperiments in a Combustion-Driven Shock Tube with an Area Change
Shock tubes are versatile and useful tools for studying high temperature gas dynamics and the production of hypervelocity flows. High shock speeds are desirable for creating higher enthalpy, pressure, and temperature in the test gas which makes the study of thermo-chemical effects on fluid dynamics possible. Independent of construction and operational cost, free-piston drivers, such as the one ...
