CELLULAR STRUCTURE OF DETONATION WAVE IN HYDROGEN-METHANE-AIR MIXTURES
Abstract
The paper reports on experimental study of cellular structure of detonation waves in hydrogen-methane-air mixtures. Experiments were performed in 6 m circular cross section tube with inner diameter of 140 mm (full diameter of 170 mm) and 0.8 m driver section tube with inner diameter of 90 mm. The initial conditions of stoichiometric hydrogen-methane-air mixtures were 1 atm and 293 K with different hydrogen content. The average detonation cell size for stoichiometric hydrogen-methane-air mixtures obtained by the smoked foil technique during experiment was calculated with 2D Fourier transform. Using the Cantera program the detonation cell width was computed as a function of initial pressure and molar methane fraction in fuel for stoichiometric methane-hydrogen-air mixture at initial temperature 295K. Results of computations were compared with experimental results.
