昇温加熱による固体の熱発火

抄録

Thermal explosion with linear time dependent boundary condition was investigated from the exact numerical analysis. Critical condition for ignition was determined by means of a new ignition criterion. This criterion was based on the distortion of the temperature profile from the stable parabolic shape. The critical condition for ignition was indicated by the curved surface in δ-B-σ space (σ is the dimensionless heating rate). Further the empirical relationship for criticality was derived from the exact numerical solution and connected with Gray's results for the traditional theory with reactant consumption admitted. Also the numerical analysis was in good agreement with the experimental results.
