In the previous paper, smoke behavior in cavity spaces were investigated experimentally and theoretically for the case where the fire sources are located at the center of the cavity space, and it is found that the temperature rise of plume at the cavity opening is well scaled by the nondimensional temperature defined as Θ=(ΔT/T_∞)/Q^<*2/3> where Q^^・^*≡Q^^・/ρ_∞C_pT_∞√<gDD^2, and the temperature is correlated by Θ= α(H/D)^β, where β=5/3,-1 and -1/3 for shallow, intermediate and deep cavity, respectively. In this paper, the smoke behavior was further investigated for the cases where the fire sources are located by a wall and at a corner of the cavity space model, and it is found that the same relationship as in case of center fire holds for the case of wall and corner fires as well. Based on this study the equations for predicting fire plume tempratures are proposed.
