Porous Medium Effect Upon Fire Suppression With
Waterfog
Author(s)
M. An & A.C.M. Sousa
Abstract
The performance of a waterfog fire suppression system in a shipboard machinery room is being
evaluated via numerical simulation using Lagrangian and Eulerian formulations for the
waterfog and gas phase, respectively. The fire in one fuel pan is located on the floor
immediately under the deck plate, and the influence of deck level obstructions, such as
perforated plates, pipes and cables, upon the fire extinguishment capability of the waterfog is
investigated by modelling these obstructions as porous medium. The parametric study
conducted produces consistent results for the cases tested in what concerns pan temperature
and fire suppression. Increasing blockage yields increasing values for these parameters, and,
on a tentative basis, it is discussed the appropriate placement of nozzl
