Conditions for Spherical Detonation in Hydrogen-Oxygen Mixture

Section: Plasmas and gases
Original Author's Text: Ukrainian

Abstract: Initial detonation conditions required for fast chemical reactions to take place at the front of a spherical explosive wave have been determined. A simple relation describing the critical detonation temperature for various pressures in the hydrogen-oxygen mixture was obtained. Using the known formulas for a shock transition, the critical temperature was coupled with the initial conditions in a static environment, such as the pressure, temperature, and hydrogen content in the mixture.

Key words: gas dynamics, a strong point explosion, blast, detonation, the system of Hugoniot equations, Semenov formula, Chapman–Jouguet regime, hydrogen-oxygen mixture, Haber scheme, Lewis scheme, kinetics of chemical reactions.
