Abstract

In this paper an attempt has been made to assess how effective waste-collecting use monohull ship with conveyor in the front. Numerical investigation based on Reynolds Averaged Navier Stokes (RANS) for predicting the flow pattern characteristics, velocity contour, and ship resistance. The focus of the present study is the impact of mohohull ship front shape on waste collection in calm water through the application of numerical methods. The three variations of the front of the monohull used are hardchine type, round bilge type, and monomaran type. It is done using speed variations of 1 to 4 knots. The results show round bilge type has the smallest total resistance value than others. In addition, analysis of the flow pattern in front of mohohull shows that monomaran type is the easiest to make waste closer to conveyor. From analysis of velocity contours also shows that monomaran type has fastest to make the waste close to conveyor.
