Full-scale burning tests on studying smoke temperature and velocity along a corridor

Full-scale burning tests were conducted in a long corridor to study the variations in smoke temperature and velocity. The results were compared with the expressions proposed in the literature. It appeared that the reduction in temperature down the corridor can be fitted by an exponential function on the distance. The power law equation by Bailey et al. [Bailey, J.L., Forney, G.P., Tatem, P.A., Jones, W.W., 2002. Development and validation of corridor flow submodel for CFAST. J. Fire Prot. Engg. 22, 139-161] also agreed fairly well with the measured data for dimensionless distance away from the fire source less than 0.4 or when the distance from the fire source is less than 35 m. The distribution of velocity along the corridor can also be fairly well fitted by exponential equations.
