축소모형터널 화재모사를 위한 헬륨-공기혼합모델 연구

초록

Conducting of Reduced Scale Tunnel-Fire Experiments are not easy due to risk for fire in door. In the study, Tunnel fire were simulated by applying buoyancy of helium-air mixture to the reduced scale tunnel experiment for safety. Helium-air mixture. Velocity vectors were measured with PIV at the near fire position
