摘要/Abstract

摘要： 利用循环管路系统，对方形管道内壁面微结构对湍流减阻效果的影响进行了试验研究，研究了循环管路系统不同壁面微结构下流动的范宁系数和减阻率。试验采用的肋条结构尺寸为：肋条宽度均为1.0mm，肋高分别是h=0.3mm、0.5mm、0.7mm。试验介质为普通自来水，水温控制在25℃±0.5℃，水平管道内流体流速范围为0.03~1.80m/s。试验研究结果表明：在量纲为1的肋深h⁺处于4~15范围内，肋条壁面的范宁系数小于光滑壁面的范宁系数，肋条壁面具有减阻效果；肋高h=0.5mm肋条的减阻效果最好，最大减阻率为11.91%；粒子成像测速仪研究了不同壁面微结构下流体流动的平均速度、雷诺切应力和近壁区的涡量。实验结果表明：肋条的存在使得湍流边界层增厚，雷诺切应力减小，近壁区的涡量降低，从而达到减阻的效果。

Abstract: In the present work, the flow characteristics and drag reduction of a turbulent flow field over a riblets surface plate were investigated experimentally and compared with a smooth surface. Experimental tests were carried out in a closed rectangular duct with 1mm in width and 0.3mm,0.5mm,0.7mm in height riblets using particle image velocimetry. Tap water was used in this experiment and test temperature was controlled at 25℃±0.5℃,and the velocity was maintained between 0.03-1.8m/s. The study showed that a notable decrease in fanning friction factor for riblets surfaces can be seen at an h⁺ range of 4-15 compared with flat plate. A maximum rag-reduction of nearly 11.91 percent was acquired over the riblets surface of 1 mm wide and 0.5 mm height. Riblet can thicken the boundary layer and weaken turbulent fluctuation intensity. Furthermore,both Reynolds shear stress and vorticity and root-mean-square velocity were decreased.

Key words: wall microstructure, fanning friction factor, drag reduction rate, Reynolds shear stress, vorticity
