| Abstract | This paper describes the design and development of surfboard-fins as products for marine sports. The purpose of the research is to improve turning ability by reducing drag force on the fins. Design modification was conducted, based on conventional fins, to increase turning ability and lower drag force. Three modified center-fins and three modified side-fins were selected. The design process involved 3D-CAD fin configuration models created with ProENGINEER Wildfire and utilized computational fluid dynamics from 3D-CAD data. Solid forms, which are required in this study since fin configuration is streamlined, are difficult to use in 3D-CAD software. Therefore, a surface element software (NURBS) developed by a propeller maker in Japan was used and the fins were converted into solid forms. After producing the fin models, the performance of factors such as turning ability and drag force were calculated using computational fluid dynamics. A flow experiment was conducted using a flow water tank in Western Hiroshima Prefecture Industrial Research Institute. This report commences with an explanation of the modifications on the fin models to improve turning ability and lower the drag force. It is then followed by the flow analysis using computational fluid dynamics software and the flow experimental results. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
