This study evaluates small-scale methods of simulating postcrash fuel spill fires adjacent to fuselage open doors. Pool fires in a quiescent environment were scaled down and their radiant heat transfer through fuselage doorways evaluated. Steel ducts of 1-, 2-, 3-, and 4-foot diameter were employed as models. Analytic solutions to radiative transfer equations were developed and matched with the experimental heat fluxes at two locations within each model. The analysis demonstrates that the doorway can be treated as a radiating black body surface of 1,874 degrees Fahrenheit, and that heat fluxes to other areas around the doorway can be calculated. A comparison of heat flux to the model exterior was compared with existing full-scale fire test data. Author
