Research on the front face styling design of a ship type based on low drag coefficient

With the continuous development of modern ship technology, the design of ships is no longer limited to meeting functional requirements, but also deepens the demand for modelling. Ship exterior modelling not only affects the aesthetic characteristics of the ship, but also influences the ship's sailing resistance and energy consumption level. Based on the drag coefficient of the ship, this paper explores the influence of different configurations of ship exterior modelling design on the wind resistance of the ship, in order to provide design guidance for modern ship exterior modelling design. To this end, this paper takes the front face design of a certain ship type as an example. Based on the confirmation of the front face design by the client, the windward face of the ship type is divided into three characteristics: the ratio of the front face segmentation width, the inclination angle between the main elevation of the front face and the vertical plane, and the shape of the main elevation of the front face. An orthogonal experimental design for aerodynamic drag simulation is proposed. For the experimental combinations, a ship simulation model is established in SolidWorks, and fluid simulation analysis is conducted using StarCCM + to obtain the drag coefficient at each experimental level as the evaluation criterion.
