Abstract:

NUMERICAL FINITE DIFFERENCE FIELD MODEL WAS DEVELOPED TO SIMULATE FULL SCALE FIRES IN CLOSED VESSELS. In particular the model was developed to simulate tests in the Fire 1 Test Facility at the Naval Research Laboratory in Washington, D.C. As a first step a rectangular 3-dimensional geometry was used to approximate the actual geometry was developed. The computer code produced pressure, temperature, density, and velocity fields from given heat input data for the fires. The most important feature of the model was that it accounts for the pressure buildup due to the fire in a pressure vessel such as Fire 1 or any other closed vessel such as a submarine. Other features include surface radiation exchange and heat losses through the wall. Model results were validated with experimental data from Fire 1. The envisioned use of the model is in simulating fires in Fire 1 and eventually in submarines. Keywords Computer programs simulators ship fires Finite difference mathematical models Enclosed fires.
