The effect of boundaries on the velocity deficit and the limit of gaseous detonations

摘要: Abstract Effects of boundaries on the gaseous detonation velocity and detonability limits are examined. A generalized Karman-Pohlhausen procedure is employed to obtain a system quasi one-dimensional equations which include boundary effects correctly.
