The solutions of Wood and Adamson for steady state detonation wave structure are discussed with particular attention given to the hot boundary where combustion is complete. Unimolecular, irreversible reaction kinetics, with an ignition temperature, and small rate parameter are assumed. An alternate solution based on Wood's analysis is presented which agrees with Wood's and Adamson's results when the hot boundary Mach number is less than unity. The solution presented here does not agree with that of Wood when the hot boundary Mach number is unity. We find thatu∼ 1 + const (logx)−1asx→ 0 when the hot boundary Mach number is unity.uis the reduced velocity;xis the mass concentration of combustible.
