Drencher sprinkler discharging water curtains is proposed to divide a building into different ‘compartments’ when it is under fire. Experiments were conducted in a chamber to investigate whether radiative heat flux can be blocked, and whether smoke spreading can be prevented. Performance of the proposed design under various discharge conditions was studied experimentally. The chamber was divided into two sides by discharging a water curtain, with a fire setting up on one side. The temperature distribution, heat flux, and optical density of the two sides were measured. Experimental results showed that the water curtain might not be so effective in stopping smoke spreading but effective in blocking thermal radiant heat.
