Abstract

Smoke temperature and volume flow rate in a tunnel fire are calculated. To obtain realistic results, enthalpy of smoke which composites combustion gases and entrainment air is calculated from curvefit polynomials by temperature. A user-friendly computer program for them is also developed. This program might be used for a good engineering tool in design of fire safety and mock/reduced-scale fire tests in a tunnel.

터널화재시에 발생되는 연기의 온도 빛 발생량을 계산하였으며 연소 가스 및 동반 공기의 엔탈피를 구하기 위하여 온도로 커브피팅된 다항식을 이용하였다. 연기 온도 및 발생량을 계산하기 위한 사용자 중심의 계산 프로그램을 제작하였으며, 이 프로그램은 터널에서의 화재안전 설계를 위한 엔지니어링 도구 및 터널에서의 화재 모의시험 및 축소시험에 사용될 수 있다.
