Two different configurations of the submarine model namely; the AFF-3 configuration, which consists of bare hull and four stern rudders, and the fully appended configuration AFF-8, which is formed from bare hull, sail, and four stern rudders, have been used. Initially, for the AFF-3 configuration, a mesh independence study has been conducted. Three different cases; coarse, medium and fine meshes are investigated at small angles (0-2-4-6 degrees). After that the results have been verified, the medium mesh structure has been selected and the analyzes have been continued for larger angles (from 00 to 180 degrees). The accuracy of the obtained results was assessed by comparing them with non-dimensional experimental results. The comparison between the CFD results and the experimental results demonstrated a high level of agreement, indicating the effectiveness and accuracy of the CFD methods used in this study. After the validation studies, the maneuvering forces and moments of the AFF-8 fully appended configuration were calculated for which no prior experimental data existed in the literature. To achieve this, steady-state CFD simulations were performed using the commercial software ANSYS Fluent, and the results were presented for the same flow angles.","PeriodicalId":41280,"journal":{"name":"Journal of Eta Maritime Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135131294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The problem owner should prioritize the design or optimization on each other. In this regard, two different ways can be followed in engineering problems: firstly designing and then optimizing or using optimized parameters in the design process. In this study, the basic design parameters of a capesize bulk carrier for a specific purpose were created and exemplified on a model. The prototype development problem is handled as a multi-criteria optimization problem by creating appropriate and pareto optimal solutions. Parameter Space Investigation method was used to solve this optimization problem, and this method was applied in a program called Multi-criteria Optimization Vector Identification. As a result of the study, the design parameters of the capesize bulk carrier sample were created and the objective function criteria were obtained better than the prototype and the value in the literature.","PeriodicalId":41280,"journal":{"name":"Journal of Eta Maritime Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135131287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
