“…This was because the experiment was conducted at a 4-storey school, which had more flammable materials for the fire to emit greater heat. In another previous study, a compartment fire analysis was carried out in a small cinema hall (Valasek & Glasa, 2017). This employed three simulation materials, namely wall concrete, chair upholstery, and the inert material for other surfaces such as the door, stage, etc.…”

The polyurethane foam material is commonly used and marketed in two forms, namely flexible and rigid. Flexible foam is used as a cushion, with various applications for commercial products such as chair support. Therefore, this study aims to describe the occurrence of a fire situation in a university room filled with many polyurethane foam chairs. It also aims to provide awareness regarding potential flame hazards, by using a fire modelling method with FDS. The results showed that fires on PU foam materials produced a high HRR and a wide spread of flame and smoke. From this context, the harmful effects of the fire on the room occupants were emphasized. The results obtained are expected to support the theory of compartment fire, flame distribution in solid materials, PU Foam inferno behaviour, etc. It is also expected to provide additional fire protection and evacuation training for room occupants.

“…The simulation results indicate that the NS strategy is more efficient than the NC strategy in cases where the number of computational meshes is not equal to a multiple of the total number of cluster node cores. As a fire simulation in large complex environments is computationally demanding task requiring greater number of computational meshes [5,6,7], further research of the efficiency of MPI parallelization using greater number of computational cores will be necessary.…”

Abstract. Current fire simulation systems are capable to utilize advantages of highperformance computer (HPC) platforms available and to model fires efficiently in parallel. In this paper, efficiency of a corridor fire simulation on a HPC computer cluster is discussed. The parallel MPI version of Fire Dynamics Simulator is used for testing efficiency of selected strategies of allocation of computational resources of the cluster using a greater number of computational cores. Simulation results indicate that if the number of cores used is not equal to a multiple of the total number of cluster node cores there are allocation strategies which provide more efficient calculations. IntroductionSimulation of fires belongs to computationally demanding tasks requiring efficient realization on a HPC (high-performance computer) system. Contemporary fire simulation systems are capable to incorporate many physical and chemical processes related to fire such as combustion, pyrolysis, thermal radiation, heat transfer, turbulence, gas spread dynamics, etc. Fire Dynamics Simulator (FDS) [1] is an advanced fire simulator utilizing the knowledge of CFD (computational fluid dynamics). It numerically solves a form of Navier-Stokes equations for low-speed fire induced flows with emphasis on transport of smoke and heat from the fire. FDS has been tested and validated for various types of fires and environments. It supports four programming models: sequential model designed for sequential computers, parallel MPI (Message Passing Interface) model designed for distributed memory systems, multithreading OpenMP (Open Multi-Processing) model designed for shared memory systems and hybrid MPI&OpenMP model designed for distributed shared memory systems. In our previous research we studied the impact of parallelization on efficiency and accuracy of a corridor fire simulation [2, 3] using a single computational node of the HPC cluster at the Institute of Informatics of Slovak Academy of Sciences in Bratislava (Slovakia). The research focused on the parallel MPI model of FDS and on testing the main strategies of allocation of available computational resources to given parallel calculations. In this paper we study efficiency of the parallel MPI model for simulation of the same type of fire using greater numbers of computational meshes and nodes.

“…The aim of the project is to prepare a series of computer simulations of fires in the Povazsky Chlmec tunnel and to validate them using experimental data from onsite tunnel measurements. For the fire modelling we use the FDS (Fire Dynamics Simulator) system which is the well-known advanced free open-source software for simulation of fires in various environments with a fire field model implemented [1][2][3][4]. The system is based on CFD (Computational Fluid Dynamics).…”

Ventilation system of road tunnel is one of the most important parts of the tunnel safety equipment, especially in view of the emergency event in the tunnel with fire. Last year we presented the testing and the first in situ measurements of our project entitled “Models of formation and spread of fire to increase safety of road tunnels”. With regard to our project schedule we performed also the second in situ experiment. Other part of this paper deals with computer simulations of fires of a selected Slovak road tunnel.
