Failure and reignition of one-dimensional detonations -the high activation energy limit

摘要

The structure of failed one-dimensional detonations is derived using a high activation energy analysis.On a time scale loner than the chemical time based upon the von Neumann temeprature,high activation energy one-dimensional detonations break down into a weaker shock,a ocntact surfac espepar5atintg hot burned gases from a colder,unbruned mixture,and an expansion wave.While this leading order solution is unaffrected by chemicstty.hence self-similalr,the perturbation acounting for the chemicstry,which depends upon chemcial times,is not.
