烟囱顶与上建高度差对烟气流场分布的影响

Influence of Height Difference Between Funnel Top and Superstructure on the Distribution of Smoke Gas Flow Field

分析烟囱顶与上建高度差对烟气流场分布的影响。针对烟气流场分布,以某型散货船为模型标本,利用STARCCM+仿真软件,通过变换高度差值,得到该区域烟气流场的分布情况。通过分析表明,在船舶常用航速下,上建开口随着高度差的增加,受烟气的负面影响可以得到有效改善。为今后评估与改善船员居住区域空气质量环境、优化上层建筑布置提供了一种解决办法。

The influence of height difference between funnel top and the superstructure on the distribution of smoke gas flow field was analyzed.For the distribution of smoke gas flow field,a certain bulk carrier was chosen as a sample.Through the software STAR-CCM+,the distribution of smoke gas flow field was actualized with the height difference change.The analysis indicated that the negative influence,imposed on the openings of superstructure at service speed,could be optimized by increasing the height difference.The analysis provided a method to estimate the quality of air in the living area,optimizing the arrangement of the superstructure.
