Propagation of fire generated smoke in shipboard spaces with heat source

Abstract

The propagation of fire generated smoke and heat transfer into a shipboard space has been computationally modeled using a commercial code generated by Computational Fluid Dynamics Research Corporation (CFDRC). The space modeled was 1-158-1-L of an Arleigh Burke Class Flight IIA Destroyer. Three smoke and heat scenarios are applied to the space. For all three scenarios, the inlet used is the forward, inboard watertight 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
