The coupling with the acoustic waves is a stabilizing factor, dominant at short wavelengths for assuring a suitably large ratio of transverse wavelength to detonation thickness ...
WebThe concept of a shock tunnel with gaseous detonation driver is discussed. A detonation driver presents an alternative to a free-piston driver because comparable values of high enthalpy can be attained, however, without the fast movement of a heavy piston. Wave diagrams, pressure and temperature distributions are presented. Finally, first … WebAug 1, 2024 · The gaseous detonation modeling was achieved through a user-defined burn approach. According to the Chapman-Jouguet (CJ) theory, the detonation travels at a steady speed and the chemical reaction completes itself in the thin layer of detonation front. In the computation, as the detonation front passed several elements, the elements were ...
WebAug 27, 2024 · The gas phase occurs as compressed even to a higher rate than in gaseous detonation. In the limit of the infinite thickness of the liquid films, the bubbles are collapsing, so extreme values of temperature and pressure can be achieved inside the bubble due to the energy focusing. In the case of the finite thickness of liquid films, they are ...
