Abstract

Fire propagation is difficult for modeling due to multi-physical nature of the phenomenon including chemical reactions, species transport, participating media radiation and unstable flow regime. Many systems can use combustion, in other words, controlled fire for producing energy. Uncontrolled fire is mostly a result of an accident or a system malfunction. This work concentrates on uncontrolled fire propagation in an aircraft engine bay. Analyses investigate numerical determination of the MHSIT (Minimum Hot Surface Ignition Temperature) of the fire. Results also demonstrate effect of different parameters on MHSIT.
