In order to improve the motion capability of surface ships or submerged bodies, there is a need to reduce the fluid drag in an effort to lower the consumption of energy. Recently, on both civil and military applications, there are many practical methods proposed to reduce the drag of surface ships and submerged bodies. Coating on the surface of these objects may be the simplest and economic way to achieve better drag reduction since it will not need to change the original design and thus can be wildly applied for vehicles on or under water.
In this study, experiments on the drag reduction of models of ship and submerged body, coated with non-Newtonian polymer material on the surface, have been conducted on a circulating water channel of CCIT. Based on the comparison of drag reduction between a coating and a non-coating models, it is expected to lower fuel consumption and to make the promotion of maneuverability of both surface ships and submerged bodies due to the reduction of their drag. The experiments also show that the drag reduction using surface coating is more effective on the submerged body than on the surface ship.
