Oxyhydrogen oblique detonation supported by two-dimensional wedge

A numerical analysis is performed on the possibility of generating a standing oblique detonation (SOD) around a two-dimensional blunted wedge. The incoming hypersonic flow consists of a uniformly-premixed stoichiometric oxyhydrogen mixture diluted by 70% Argon of a Mach number higher than its Chapman-Jouguet value 4.8. Varied parameters are the nose radius, wedge angle, and the Mach number and temperature of the incoming flow. Based on the Euler equations and realistic oxyhydrogen elementary reactions, the 2nd-order-accurate explicit or implicit TVD upwind scheme of Yee-Harten gives the following different modes in SOD; (i) steady oblique coupled detonations, (ii) steady oblique decoupled detonations, (iii) oscillating but standing oblique coupled/decoupled detonations, and (iv) run-away detonations which are unable to stand in front of a wedge.
