- Abstract
- By experiments with "simulated" fire smoke, the spread of smoke from a cabin fire on HMS Visborg was studied. Main objectives were the time of smoke arrival to various places and the effect of mechanical ventilation. The smoke was generated by an oven, exhausting air heated by butane burners and made visible by salammoniac. In the report are given data of temperatures T (t) and optical density OD (t) from about 13 places. The results show a widespread extension of thin smoke, a much smaller spread of dense smoke and a short spread of high-temperature gases. The effects of mechanical ventilation was observed to result in a restricted flow along channels (corridors etc) compared to the non-ventilated case.
