摘　　要：[目的]旨在研究舰船舱室环境油雾在金属和织物表面的沉降特性。[方法]在试验舱内释油雾,让其在目标表面上沉降,称量表面沉降前后的质量差即为表面上的沉降质量,以此来对比不同朝向、不同材质表面的沉降特性;将水平向下表面的沉降合理假设为气相沉降,估算其贡献大小,并计算颗粒相的沉降速度。[结果]在朝向方面,金属水平向上表面的沉降质量分别是竖直和水平向下表面的3.98倍和4.66倍,织物水平向上表面的油雾沉降质量是竖直和水平向下表面的1.08倍和1.20倍;在材质方面,织物水平向上、竖直和水平向下表面的沉降质量分别是同朝向的金属表面的49.1倍、169.8倍和155.5倍。估算表明,对于金属水平向上和竖直表面,气相沉积的贡献分别为21.5%和79.2%;对于织物的水平向上和竖直表面,则约为90%。[结论]研究表明,舰船舱室环境油雾在织物表面的沉降远强于在金属表面的沉降;在金属水平向上表面的沉降远大于竖直表面和水平向下表面;在3种朝向的织物表面的沉降差别并不明显;无论何种材质和朝向,气相沉降都不可忽视。对于舰船舱室环境,气相沉降占据主导作用。[Objective]This study focuses on the deposition characteristics of oil mist on metal and fabric surfaces in ship cabin.[Methods]Oil mist is released in an experimental cabin and allowed to deposit on the target surfaces.The mass difference before and after deposition on the surfaces is weighed to determine the deposition mass,and the oil mist deposition characteristics of surfaces with different orientations and materials are compared.The deposition on the horizontal downward surface is reasonably assumed to be gas phase deposition.Its contribution is then estimated and the particle phase deposition velocity is calculated.[Results]The deposition mass on the horizontal upward surface of the metal is 3.98 times and 4.66 times greater than that on the vertical surface and horizontal downward surface.For fabric surfaces,the deposition mass on the horizontal upward surface is 1.08 times and 1.20 times greater than that of the vertical surface and horizontal downward surface.For material comparison,the deposition mass on the horizontal upward,vertical and horizontal downward surfaces of the fabric is 49.1 times,169.8 times and 155.5 times greater than that of the metal surface facing in the same direction respectively.Estimates show that the contribution of phase deposition to the metal horizontal and vertical surfaces are 21.5%and 79.2%respectively.The contribution of phase deposition to the fabric surfaces is about 90%.[Conclusions]The oil mist deposition on fabric surfaces is much stronger than that on metal surfaces.The deposition on the metal horizontal upward surface is much greater than that on the vertical surface and horizontal downward surface.The deposition differences between the fabric surfaces in the three orientations are not significant.Regardless of orientation or material,gas phase deposition cannot be ignored as it plays a dominant role in ship cabin environments.
