three-dimensional surface structure for reduced resistance and improved heat transfer

摘要

In order to improve the flow properties of a surface the invention proposes a surface along which a medium flows, said medium consisting of a gas, a liquid, a two-phase mixture, or a mixture of multiple phases, wherein said surface comprises dimples, the edges of which are rounded, thereby forming a central dimple area and at least one curvature area for each dimple, which continuously connects the dimple to the surrounding surface.The invention further proposes various devices comprising the surface, a layer comprising the surface, and also methods for producing the surface.
