Abstract: Tests to see how smoke from fires fills large spaces on a ship were carried out. Then experimental fires were simulated with a CFD package based on a modified set of Navier-Stokes equations for thermally driven buoyant flow and Large Eddy Simulation (LES) while also using a two-layer zone model. Descent law and temperature distribution of the smoke were analyzed. Experimental results show that smoke layers descende quickly and smoke temperature is low. As a result, detectors and sprinkler systems which are activated by temperature are at a disadvantage. Computed results and experimental results were compared with each other. Results show that the smoke filling process can be reasonably simulated by large eddy simulation with a zone model. A fire in its growth stage and during its decay period can be described by a t2 curve. Smoke layer height can be read by both the thermocouple method and the camera method, but reasonable results can be obtained from the thermocouple method alone.
