Estimation and comparison of towing tank resistance for round bilge fishing ships using differents numerical techniques

This degree thesis deals with the estimation of towing tank resistance of fishing vessel with round bilge. First, a state of art of fishing vessel is presented. Second, the usual statistical methods to predict the towing tank resistance of fishing vessel are analyzed. Third, a typical fishing vessel with round bilge is designed. Some parameters of designed fishing vessel are analysed. Fourth, the statistical method are applied to fishing vessel. The results are compared. Fifth, a towing tank analysis with CFD code Tdyn is carried out. The results of CFD and other numerical mentod are compared. Finally some conclusions are presented
