Deposition characteristics of oil mist on metal and fabric surfaces in ship cabin
摘要
Abstract
[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 materi-als 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 horizont-al upward surface is 1.08 times and 1.20 times greater than that of the vertical surface and horizontal down-ward 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 sur-face 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 fab-ric surfaces in the three orientations are not significant.Regardless of orientation or material,gas phase depos-ition cannot be ignored as it plays a dominant role in ship cabin environments.关键词
