Fundamentals of metals ignition in oxygen
Ignition is associated with the thermal energy input into the system occurring at a rate faster than thermal energy is being lost to the surroundings. The solution of an idealized model for ignition at a plane metal surface characterizes the material in terms of the property thermal inertia, kpc. The thermal inertia for six metals Al, Cu, Fe, Mg, Ni and Ti, at their ignition temperatures is compared to the relative burn resistance of the metals in terms of BRmp, BRbp, threshold pressure, resistance to ignition by particle impact and frictional heating ignition, pv. Thermal inertia is in agreement and appears to be suitable property for characterizing metals ignition. In addition, considerations for relaxing the assumptions associated with the idealized model are described and thermal inertia is still a valid characterization for the material.
