本文用数值方法研究了表面结构对沟道流的表面摩擦阻力减小的可能性。在这种情况下,与典型的波纹尺寸相比,具有高宽高比的表面结构在层流和湍流状态下进行了研究。一般来说,发现在两种流动状态下流动阻力的减小是可能的。(©2012 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
The possibility of skin‐friction drag reduction in channel flows due to surface structures is investigated numerically. In this context, surface structures with a high width to height ratio compared to the typical dimensions of riblets are studied in the laminar as well as in the turbulent flow regime. In general, it is found that a reduction of the flow resistance is possible in both flow regimes. (© 2012 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
