Abstract

See full text

A raised structure for reducing frictional drag due to viscosity of a flow toward an object in a direction defining an acute angle with a leading edge of the object. The raised structure includes raised bodies configured to be provided on a surface of the object at the leading edge on a downstream side of a stagnation point of the flow. A height of each raised body changes along a convex curve, and the raised bodies are arranged in an array to define a first uneven shape changing periodically in a first cross section configured to have a constant distance from the stagnation point and be orthogonal to the surface, and a second uneven shape changing in a second cross section configured to be orthogonal to a line composed of the stagnation point and the first cross section, the second uneven shape having concave and convex portions that change periodically.
