How is watermist entrainment utilised in firefighting?

Traditional fire sprinklers use the cooling ability of large droplets of water and wetting of surfaces to fight fires below. In contrast water mist systems, like Automist, use the inerting effect of water vapour. By deploying watermist lower down they use the recirculating movement found in the typical flow pattern of a domestic fire. Small droplets are drawn into the turbulence caused by the fire and entrained into the fire plume. So it is effective on concealed fires shielded from the nozzle, contained within a cabinet, under a table, or in a tumble dryer. This is more efficient than deploying watermist from the ceiling where you must penetrate the hot layer and are subject to evaporative loss before you can reach the fire plume.
