Compared with the space on the ground, if there is a fire in the urban complex underground space, the loss will be greatly harmful. In addition, the complex underground space is usually connected with other large space areas and densely populated. Once a fire occurs in the complex underground space, it will cause huge property losses and casualties. In order to reduce the risk of fire, it is necessary to deeply understand the development rules and characteristics of fire in the complex underground space of the city. This article has mainly carried on the following work: (I) A particularly complex model of the multi‐storey subway station was built. On this basis, three groups of comparative experiments were conducted to study the effects of fire power, fire location and smoke control system on fire development, and the conclusion that fire location is the most important factor for fire development was obtained; (II) In order to explore the entire space fire and the local space fire, CFD (Computational Fluid Dynamics) is used to build a large‐size fire model and a small‐size fire model respectively; (III) Multiple detector data as temperature slices were built, and it is expected to make full use of the simulation data to deduce the important index of fire location in the early stage of fire. All of the works in this paper will provide reference experimental data for the prevention and firefighting of a sudden fire in the complex underground space.

“…Other studies focus on evacuation planning [9], evaluating and optimizing evacuation plans [10][11][12][13], and studying human behavior in emergencies [14,15]. According to [16], the study constructs a BIM-FDS building fire simulation model to reveal the fire smoke dispersion law under the coupling of the typical building structure and fire protection systems. According to [17], the authors proposed a new way for a smart building fire evacuation and control system based on the IoT to direct individuals along an evacuation route during fire incidents efficiently.…”

Emergency evacuation is of paramount importance in protecting human lives and property while enhancing the effectiveness and preparedness of organizations and management agencies in responding to emergencies. In this paper, we propose a method for evacuating passengers to safe places with the shortest possible evacuation time. The proposed method is based on a multi-level multi-agent MAS-GiG model combined with three problems. First, constructing a path map to select the shortest path; second, dividing the space of the experimental environment into smaller areas for efficient management, monitoring, and guiding evacuation; the third, adjusting the speed to handle collision issues and maintain distance between two or more groups of evacuees while moving. We extend our previous study by establishing groups based on the location of passengers and using a MAS-GiG model to guide evacuation. We compare the proposed method with our previous method to provide specific evaluations for the research and research in the future. We tested two methods in the departure hall, first floor, Danang International Airport, Vietnam.

“…With this aim, authors such as Feenstra et al [3] have developed methodologies that allow CFD fire simulations and thermo-mechanical models to be coupled in two ways. Currently, methodologies based on machine learning are also being developed to include the use of CFD models in the structural analysis of fire [4], as well as the use of building information modeling (BIM) in the development of three-dimensional models and the management of all building information [5].…”

Numerical simulations, based on the theories of computational fluid dynamics and combustion, are currently a powerful tool in the field of fire engineering. Field models allow us to analyze key aspects such as the integrity of buildings and safety. However, it is fundamental to define strategies that allow engineers to obtain a balance between the precision of the results and the computational cost. One of the most relevant sub-models is the turbulence model. This paper presents the research carried out in the field of two-dimensional computational simulations of turbulent dilatable flows to evaluate the behavior of diffusion flames, hot gases, and smoke produced in accidental fires. Several computational simulations have been performed using direct numerical simulations and large eddy simulation turbulence models in the two-dimensional field, analyzing the ability of the models to correctly characterize the transport of hot gases and the behavior of the thermal plumes if the grid resolution is adequate to the physics of the problem. Additionally, several three-dimensional models have been developed to contrast and validate the results obtained in the two-dimensional simulations. In order to validate the capacity to develop a qualitative analysis of two-dimensional models in fire engineering, an evaluation criterion is presented based on the frequency spectral analysis to study the capacity of each type of turbulence model to accurately capture the vorticity of these dilatable flows.
