Аннотация

Ship cabin fire accidents, on the one hand, might badly affect the integrity of ships and the safety of people, on the other hand, possibly result in the loss of safety-related equipment functions. Therefore, it is sensible to evaluate fire risk in ship cabins. Based on full-scale experimental tests, fire simulations by CFAST and FDS were conducted in this study to evaluate the effect of the size of the supply opening on smoke exhausts, and the size was changed by adjusting the upper height of the supply opening in the fullscale experimental tests and fire simulations. According to the experimental configurations, six groups of tests in this study were conducted by changing the upper heights as 0.1, 0.3, 0.5, 0.7, 0.9, and 1.1 m, and smoke layer temperatures, and smoke layer heights from experimental tests and fire simulations were selected as several indicators for the evaluation. By comparing full-scale experimental tests with fire simulations, it was shown that different sizes of natural supply vents have different effects on the effectiveness of smoke exhausts. More specifically, having a supply opening, compared with no supply opening, can effectively reduce smoke layer temperatures and increase smoke layer heights, which has been proven by full-scale experimental tests and fire simulations in this study.
