Parameters of Flow Behind Gas Detonation Front in Rough Pipes

Results are given of a numerical solution to the flat nonstationary problem on the detonation propagation in rough pipes taking into account friction and heat sink into channel walls. An asymptotic solution for parameters distribution behind the detonation wave front is obtained and analyzed. Analytical approximations are adjusted for the asymptotic distributions of pressure and mass velocity in detonation products which can be used under a certain condition as initial data in solving problems on the formation and propagation of shock waves in rough pipes.
