“…Using specific techniques, these models can simulate phenomena such as heat and combustion products, radiation and convective heat transfer between gases and solid surfaces, the fire behavior and optimal activation mode of fire safety devices (sprinklers, heat detectors, smoke sensors, etc.). Complex phenomena can be studied at an advanced level: pyrolysis, fire development and its evolution in intensity, possibilities of fire suppression by using water extinguishing systems [8,9].…”

Investigating the fire type events is characterized by a high degree of complexity, due to the fact that it has to find answers to aspects coming from multidisciplinary fields: technical-scientific, legal, organizational, psychological, etc. The management of the findings, the analyzed samples, and the resulting data implies a series of complex activities, based on the use of advanced procedures and techniques. Fire investigation aims to determine the source of ignition and all the components that contribute to define the cause of the fire, to assess the motivations of the involved persons and to decipher the mechanism of heat transfer or burning processes that describes the propagation and development of a fire. Often, in order to understand the mechanism of the pyrogenic phenomenon, the following approaches are used in the current practice: technical-scientific expertises, reconstruction of the event on the field or in the laboratory, sample analysis, and, last but not least, computer simulations. This paper aims to highlight the role of the numerical models used in the field of fire safety, respectively in the elaboration of the post-event, technical-scientific expertises, by presenting some results obtained from the computer simulations, used to substantiate the fire mechanism and to formulate the conclusions.

“…In this study, the numerical simulations were performed using the Fire Dynamics Simulator (FDS) version 6.0.2, which is a well-recognised software in the fire engineering community. There have been many successful case studies of fire scene reconstruction and forensics using FDS [20,21]. Furthermore, there are ongoing developments to extend the application to wildland fires by incorporating large-scale fire propagation models [22].…”

Recent high-profile building fires involving highly-combustible external cladding panels in Australia as well as Dubai, China, and the United Kingdom have created a heightened awareness by the public, government, and commercial entities to act on the risks associated with non-compliant building structures. In this paper, a database of fire events involving combustible aluminium composite panels was developed based on (i) review of relevant major fire events in Australia and other countries, and (ii) numerical simulation of the ignitability, fire spread, and toxic emissions associated with composite panels. Through the application of large-eddy-simulation (LES)-based computational fire field models, the associated risks for a standardized two-storey building with external cladding was considered in this study. A total of sixteen simulation cases with different initial sizes of the fire and different air cavity widths in the exterior cladding assembly were examined to investigate the tolerable situations and their influences. It was discovered that for most cases, with an initial fire size greater than 400 kW/m−2, the fire will spread from the first to second floor before the allowed egress time period.

“…Nowadays, numerical simulations using CFD techniques are commonly applied for a wide range of fire safety assessments such as compartment and wildland fires [30][31][32][33], fire forensic investigations [34], solid combustibles [35], toxic gas approximations [36,37], and many other fire phenomenon [38]. Nevertheless, smoke movement and visibility simulations remain the most widely adopted in the construction and fire safety engineering industry.…”

In this study, a Large Eddy Simulation (LES) based fire field model was applied to numerically investigate the effectiveness of smoke control using smoke vents and curtains within a large-scale atrium fire. Two compartment configurations were considered: the first case with no smoke curtains installed, while the second case included a smoke curtain at the centre of the compartment to trap smoke. Based on the thermocouple results, it was found that the model predicted the gas temperature near the fire particularly well. The time development and heat transfer of the gas temperature predictions were in good agreement with the experimental measurements. Nevertheless, the gas temperature was slightly under-predicted when the thermocouple was further away from the flaming region. Overall, it was discovered that the combination of a smoke curtain and ceiling vents was a highly effective natural smoke exhaust system. However, under the same vent configuration, if the smoke curtain height is not adequate to completely block the spread of smoke, it significantly reduces the pressure differential between the compartment and the exterior, causing reduced flow rates in the outlet vents.
