Studies of Cooling Effects of Sprinkler Spray on Smoke Layer

Li, S.C., Yang, D., Huo, R., Hu, L.H., Li, Y.Z., Li, K.Y. and Wang, H.B., 2008. Studies of Cooling Effects of Sprinkler Spray on Smoke Layer. Fire Safety Science 9: 861-872. doi:10.3801/IAFSS.FSS.9-861


An experimental study was performed to measure the cooling of a smoke layer by water sprays. This was followed by the development of a mathematical model based on the theory of Chow and Tang. The predictions of the model agree well with the experimental measurements. Water sprays investigated in the present work provided significant cooling of the smoke layer. We observed little effect of increasing the water pressure from 50 to 100 kPa on the cooling of the smoke layer.
