Propagation of Fire Generated Smoke in Shipboard Spaces

Abstract

The propagation of fire generated smoke into a shipboard space has been computationally modeled using a commercial code generated by Computational Fluid Dynamics Research Corporation (CFDRC). This study was based on space 01-163-2-L of an Arleigh Burke Class Flight IIA Destroyer. However, with changes, the model can be reconfigured to represent other shipboard spaces. Multiple smoke scenarios are applied to the space. For all scenarios, the inlet used is forward water tight door. Smoke enters the upper half of the door, while air enters through the bottom half. The temperature of the inlet fluids is altered to observe its effect on propagation. In the last scenario, the floor temperature is isothermally held at 1200 K to simulate a fire in the space below. The results of this scenario shows that extreme temperatures of adjacent spaces has minimal effect on propagation. The overall goal of this study is to show how computational methods can be used to model propagation of smoke in shipboard spaces.
