| The advantages of water suppression technology, including environment friendly, fast extinguishment, low water consumption, and wide application, have received considerable attention in international fire safety research field. Based on this advanced fire protection technology, experiments of water mist interaction with small-scale petroleum and methanol pool fires are carried out. Thermocouples temperature measurement systems and digital video camera are employed to measure the time-dependent temperature profiles, in both the liquid and gas phase. Parametric studies are performed to determine the effect of the pre-ignition time, gas pressure and types of liquid fuel on entrainment and suppression of pool fires.A zeroth model of liquid fuel temperature profile is developed. The results are reported in terms of liquid pool mean temperature change with time, and the numerical results agree well with the experimental data.A two-phase model of water mist interaction with liquid pool fires is developed. Commercial software FLUENT is used to solve both the combustion and fire suppression processes. Typical parameters such as temperature, species concentration and combustion rate are investigated in terms of time change in the radial direction.
