In this study, a FDS(Fire Dynamics Simulator) was used to analyse the effect of the mesh resolution on the fire spread phenomenon of a cable tray fire. The heat release rate calculated for different mesh resolutions was found to be higher with increasing , and predicted the experimental results relatively accurately, with a minimum simulation time of about 13 hours depending on the mesh resolution. Among the various fire modeling methodologies, the mesh resolution did not affect the simulation results when the fire spread rate was set, and the mesh resolution had a significant effect on the simulation results when the ignition temperature was set for the fire to ignite.

본 연구에서는 화재역학시뮬레이터를 활용하여 전선 트레이 화재의 연소 확산 현상에 미치는 요소망 해 상도의 영향을 분석하기 위해 수행하였다. 다양한 요소망 해상도에 따라 계산된 열방출률은 요소망 해상도가 증가 할수록 높게 측정되고 오차 범위 약 14%로 실험결과를 잘 예측하였으며, 요소망 해상도에 따라 계산에 소요된 시 간은 최소 약 13시간이 소요되었다. 전선 트레이 화재에 대한 화재모델링 방법 중 화재 확산 속도가 설정되는 경 우 요소망 해상도는 해석 결과에 영향을 미치지 않는 것으로 예측되었다. 그러나 화재가 발화되기 위한 점화 온도 가 설정된 경우 요소망의 해상도는 해석 결과에 큰 영향이 있는 것으로 분석되었다.

Ever since next generation convergence technology became one of the most important industries in the nation, computing professionals have encountered a growing number of challenges. Along with scholars and colleagues in related fields, they have gathered in avariety of forums and meetings over the last few decades to share their knowledge, experiences and the outcome of their research. These exchanges have led to the founding of the International Next-generation Convergence technology (INCA) on December 1, 2015. INCA was registered as an incorporated association under the Ministry of Information and Communications. The main purpose of the organization is to improve our society by achieving the highest capability possible in next generation convergence technology.
