Fire simulation has been developed for decades to analyze fire cases and provide a tool to study fundamental fire dynamics and combustion. There are three way of fire simulation which are a full scale simulation, an experimental simulation and a computational simulation. In case of a full scale simulation, because a higher cost, a higher risk, more efforts are needed, a demand for it has been decreased. But recently a demand for an experimental simulation and a computational simulation has been increased. A computational simulation has several advantages; lower cost, short period, many case studies, more visual results, a quantitative result and etc. FDS(Fire Dynamics Simulator) which has been developed in BFRL(Building and Fire Research Laboratory), NIST(National Institute of Standards and Technology) is a popular world wide code for fire simulation. Lack of accurate predictions by the model could lead to erroneous conclusions with regard to fire safety. All results should be evaluated by the informed judgment of the qualified user.

In the present study, a forest fire spread was simulated with a three-dimensional, fully-transient, physics-based, computer simulation program. Physics-based fire simulation is based on the governing equations of fluid dynamics, combustion and heat transfer. The focus of the present study is to perform parametric study to simulate fire spread through flat and inclined wildland with vegetative fuels like trees or grass. The fire simulation was performed in the range of the wind speeds and degrees of inclination. From the results, the effect of the various parameters of the forest fire on the fire spread behavior was analyzed for the future use of the simulation in the prediction of fire behavior in the complex terrain.

To improve the fire safety of ships, it is required to prepare the systematic design guideline for fire protection and the way of assessing fire characteristics quantitatively. The introduction of simulation technique based on fire engineering is useful to assess fire safety performance quantitatively. Fire simulation tools are currently developing with U.S.A., Europe and Japan as a leader. Most of current fire simulation tools were developed for building or inland structure. Therefore it is required validation process and development of data base to apply maritime environments. In this paper, I/O parameters of simulation tools such as CFAST and BRI2002 of zone model and FDS and KFX of field model analysed, and designed data base considering maritime environment. The fire simulation for the pool fire model of engine room and its adjacent compartments is performed and evaluated the results.

논문에서는 방화셔터와 피난계단이 존재하는 실내 환경의 화재 시뮬레이션을 실시하여 방화셔터와 화재 확산 사이의 관계를 분석하였다. 화재 시뮬레이션용 상용 소프트웨어인 FDS(Fire Dynamics Simulator)를 사용하여 가상으로 설정한 실내 로비에서 화재 규모와 방화셔터의 개폐 여부를 변화시켜 가면서 모의실험을 실시하였다. 실험을 통해 화재실 벽면과 계단 입구의 온도 변화, 이산화탄소 농도 변화, 연기의 확산 등의 변수들을 구하고 결과를 검토하였다. 피난계단에서 온도와 이산화탄소의 분포는 화재규모와 개구부의 개폐 여부와 별 상관이 없으나, 방화셔터의 부분 하강이 연기의 확산을 막고 있음을 알 수 있었다.

The present study investigates the effect of fire growth model on fire development characteristics in a carriage. The parallel processing version of FDS code is used to simulate the fire driven flow in a carriage and two types of fire growth model which are flame spread model and t$^2$ model are examined for the same geometrical condition. The heat release rates(HRR) of both model are similar each other until 30 s after ignition, but the flame spread model predicts 5 times higher than those of the t$^2$ fire model during the quasi-steady fire period. Maximum heat release rate in the case of flame spread model reaches about to 12 MW at 100 s after fire ignition. Also, various database of fire properties for combustible materials and more elaborate combustion model considering the flame spreading phenomena are required for better predictions of fire development characteristics using numerical simulation.

본 연구에서는 실제역사화재 사고인 대구지하철화재사고를 참고하여 화재시뮬레이터의 경계조건으로 시뮬레이션을 수행 하였다. 화재시뮬레이션의 경우는 총 지하 3층의 역사 중 사망자가 가장 많이 발생한 지하3층 역사와 지하2층 대합실까지 모델링하여 시뮬레이션을 실시하였다. 화재시뮬레이터는 CFAST와 FLUENT를 이용하여 수행하였으며, CFAST의 경우는 총 29개의 Zone으로, 지하3층 역사 18개, 지하2층 역사 11개로 나누어 시뮬레이션 하였다. FLUENT의 경우는 총24개의 Zone으로 나누었으며, 지하승강장의 경우는 CFAST의 Zone과 동일하게 설정하였다. 2개의 시뮬레이터에서 나온 결과값들을 비교하여 지하역사 화재시 적용가능성 여부를 연구하였으며, 피난시뮬레이션인 EXODUS를 이용하여 각각의 화재시뮬레이션의 결과를 EXODUS의 HAZARD 경계조건으로 하여 피난 시뮬레이션을 진행 하였다. 화재영향의 적용은 CFAST의 경우 EXODUS로 자동적으로 화재 DATA가 Lode 되는 방식으로 하였으며, FLUENT의 경우는 화재시뮬레이션 OUT DATA값들이 EXODUS와 호환이 어려우므로 직접 결과값들을 수식으로 변환하여 EXODUS HAZARD에 적용하여 승객피난시뮬레이션을 수행하였다. 또한 이를 실제 대구지하철화재사고와 비교분석하였다.

In December 2017, a fire at the Jecheon Sports Center caused 29 deaths and 40 injuries, and about 2 billion won in property damage. It is a facility used by unspecified people as a publicly used establishment with a piloti structure. The damage was expanded due to the ignition of combustible exterior materials, Lack of fire protection in horizontal and vertical penetrations. Although legislation has improved since the fire, it is not retroactively applied, increasing the risk of fire in existing buildings. Accordingly, it is necessary to examine the case of the Jecheon Sports Center fire and draw out the problems. In this study, the fire simulation results and the Jecheon Sports Center fire are comparatively analyzed and used as basic data for fire reduction measures in publicly used establishment. As a result of the fire simulation drive, in the case of the second floor, the room temperature exceeded the human life safety standard of 60 ℃ after about 700 seconds had passed. In the case of three floor, it is predicted that the indoor temperature will exceed about 350 ℃. and temporary complexation will occur in the indoor combustibles.

There is a need to analyze various factors in evacuation safety assessment of building in fire. In the current performance based design, evacuation safety assessment in case of fire is being conducted through the simulation as FDS and Pathfinder. However, the location and size of the door, the location of evacuation in the event of a fire are not considered when design. Accordingly, it is difficult to determine the worst case scenario considering the actual fire. Therefore in this study, in this study, we will propose an appropriate evaluation plan through simulation considering the worst-case scenario that may occur in case of fire.
