| Summary: | The objective of this study is to address issues through the use of experiments and
simulations in order to assess the efficacy of water mist in enclosed spaces with
different types of fuels. A series of measurements were conducted to analyze the
performance of water mist in extinguishing fires, considering factors such as
extinguishing time, temperature reduction, and burning duration. To measure the
average room temperature in the gas phase, a type K thermocouple with a diameter
of ???????????????????????? was utilized. The water mist, with a median droplet size of ????????????????????????, was
sprayed from the indoor ceiling. The simulation involved the use of Ethanol,
Methanol and Gasoline RON 92 as fuels, and was conducted using the Fire
Dynamics Simulator (FDS), an open source-based computational fluid dynamics
model for fire flow. Uniform grid size of 1 cm throughout the computational
domain. The results of the test indicate that the type of fuel used can impact the fire
extinguishing capabilities of water mist in an enclosed space. |
