“…It is usually evaluated in the literature by means of CO 2 concentration [16,17] as well as temperature measurements [18][19][20][21][22], the latter being the most used due to the ease of its measurement. There are many different temperature methods to evaluate the smoke layer interface in the literature, such as the n-percent method proposed by Cooper et al [18], the upper zone averaging and mass equivalency by Quintere et al [19], the maximum gradient method by Emmons [20], the Janssen method [21] or the least-square method by He et al [22]. All these methods, except the least-square method, present a certain grade of empiricism, because of that the least-square method has been used in this paper to compare the smoke layer interface both numerically and experimentally.…”

Abstract. An experimental and numerical comparison of new full-scale atrium fire tests in the 20 m cubic atrium with four different heat release rates (1.7 MW, 2.3 MW, 3.9 MW and 5.3 MW) is presented. Different exhaust conditions (steady and transient extraction rates) and different make-up air configurations (symmetric and asymmetric) are assessed. Temperature measurements in the near (fire plume) and far field (close to the walls) have been recorded by means of 59 thermocouples. The smoke layer interface is also estimated by means of a thermocouple tree with 28 measurements using the least-square and the n-percent methods. The simulations have been conducted using FDS (version 6, Release Candidate 3). The comparison with the simulations shows average discrepancies lower than 32% and 11%, for the near and far field temperatures, respectively. A discrepancy lower than 5% (1 m) is obtained by both methods for the smoke layer height when the steady state is reached. Finally, a slower response to an increment on the exhaust rate is predicted on the smoke layer, being more perceptible for high heat release rates.

Force-ventilation compartments are a common environment for fire growth in sealed or high-rise structures. Currently, no method exists for reliably estimating the fire hazard in these enclosures. Using data from compartment fires in the forced ventilation facility at the Lawrence Livermore National Laboratory (LLNL), a simple correlation has been developed following the methods of McCaffrey, Quintiere and Harkleroad. The upper layer temperature rise above ambient, LIT = Tu -Too, is given as a function of: the fire heat release rate, G, the compartment mass ventilation rate, m, the gas specific heat capacity, cp,
