Abstract

In order to compare the frictional resistance of three kinds of ship’s hull coatings (Foul Release, SPC copper, SPC TBT) in the unfouled conditions, the numerical studies have been made. Simulations have been carried out for different Reynolds numbers in the range of 2.85 × – 5.5 × based on the plate length and flow velocity. Antifouling coatings have a larger mean roughness than Foul Release. The results have indicated that frictional resistance coefficient of Foul Release test plate is lower than SPC copper and SPC TBT test plates. The total resistance obtained by computational fluid dynamics has been compared with the experimental data and good agreement in results has been found which those have shown the ability of CFD modeling in calculating of fluid flow resistance by considering the coating characteristics.

涂有污垢释放和防污涂层表面湍流边界层的数值模拟

为了比较三种船体涂层(防污涂层、SPC铜涂层和SPC TBT涂层)在未受污染条件下的摩擦阻力，进行了数值研究。在2.85 × ~ 5.5 ×的雷诺数范围内，根据板长和流速进行了数值模拟。防污涂层的平均粗糙度比去污涂层大。试验结果表明，除臭试验板的摩擦阻力系数低于SPC铜和SPC TBT试验板。将计算流体力学得到的总阻力与实验数据进行了比较，结果吻合较好，表明了CFD模型在考虑涂层特性的情况下计算流体流动阻力的能力。

期刊介绍： TJPRC: Journal of Naval Architecture and Marine Engineering (JNAME) is a peer reviewed journal and it provides a forum for engineers and scientists from a wide range of disciplines to present and discuss various phenomena in the utilization and preservation of ocean environment. Without being limited by the traditional categorization, it is encouraged to present advanced technology development and scientific research, as long as they are aimed for more and better human engagement with ocean environment. Topics include, but not limited to: marine hydrodynamics; structural mechanics; marine propulsion system; design methodology & practice; production technology; system dynamics & control; marine equipment technology; materials science; under-water acoustics; satellite observations; and information technology related to ship and marine systems; ocean energy systems; marine environmental engineering; maritime safety engineering; polar & arctic engineering; coastal & port engineering; aqua-cultural engineering; sub-sea engineering; and specialized water-craft engineering. International Journal of Naval Architecture and Ocean Engineering is published quarterly by the Society of Naval Architects of Korea. In addition to original, full-length, refereed papers, review articles by leading authorities and articulated technical discussions of highly technical interest are also published.
