초록

수소는 다른 연료에 비해 에너지효율이 높고 유해물질이 배출되지 않아 미래의 청정에너지원으로 인식되고 있다. 그러나 수소는 밀도가 낮아 운반 및 저장시에 부피가 커서 압축하거나 특별한 운반체를 사용해야 하며, 공기중에 노출 시 화재나 폭발의 위험성이 있다. 수소-공기 혼합물의 폭발에 관한 실험이나 수치해석적 연구가 진행되어 오고 실물 수소 충전소를 대상으로 한 폭발 시뮬레이션에 관한 연구사례는 극히 드물다. 본 연구에서는 실제 수소 충전소를 대상으로 Lidar 스캐닝을 수행하여 point cloud 데이터를 획득하고 수소 충전소 3 차원 구조 모델을 작성한다. 3 차원 구조모델은 Ansys 사 AUTODYN 에 적용되어 수소 충전소의 수소폭발을 가정한 TNT 등가량의 폭발 시뮬레이션을 실시하고 주변에 전파하는 폭발압력을 계산하여, 수소 충전소 폭발에의한 주변 보안 건물의 안전거리에 관한 정보를 제공한다.

Hydrogen is a fuel having the highest energy compared with other common fuels. This means hydrogen is a clean energy source for the future. However, using hydrogen as a fuel has implication regarding carrier and storage issues, as hydrogen is highly inflammable and unstable gas susceptible to explosion. Explosions resulting from hydrogen-air mixtures have already been encountered and well documented in research experiments. However, there are still large gaps in this research field as the use of numerical tools and field experiments are required to fully understand the safety measures necessary to prevent hydrogen explosions. The purpose of this present study is to develop and simulate 3D numerical modelling of an existing hydrogen gas station in Jeonju by using handheld LiDAR and Ansys AUTODYN, as well as the processing of point cloud scans and use of cloud dataset to develop FEM 3D meshed model for the numerical simulation to predict peak-over pressures. The results show that the Lidar scanning technique combined with the ANSYS AUTODYN can help to determine the safety distance and as well as construct, simulate and predict the peak over-pressures for hydrogen refueling station explosions.
