Abstract
In order to reduce the surface resistance of underwater vehicles, a new type of composite skin is proposed by combining flexible skin with flexible and miniaturized steel wire vibration isolators. Using ANSYS fluent and transient structure to conduct bidirectional Fluid-structure interaction and drag reduction performance of the skin was studied. The effects of flow velocity and material parameters on its drag reduction performance were discussed. Research results indicate that compared with the steel plate without skin, the resistance of the skin is significantly reduced. Analyzing its mechanism, the wall shear stress after laying the skin is reduced. This study provides a new approach for the design of skin for underwater vehicles.
