Control of near-wall coherent structures in turbulent boundary layers by synthetic jets

This data includes two turbulent boundary layers over a flat plate and eight turbulent boundary layers with local forcing. The turbulent boundary over a flat plate was measured at 1239 mm and 1295 mm from the leading edge. All the turbulent boundary layers with local forcing were measured at 1295 mm from the leading edge.All measurements were conducted at one free stream velocity of 5.5 m/s and at the Reynolds number of Reθ ≈ 1132 where θ was the momentum thickness of the turbulent boundary layer over a flat plate.The local forcing frequencies were 100, 150, 200, and 250 Hz, which equates to the non-dimensional frequencies of 0.025, 0.038, 0.050, and 0.063, respectively. The forcing amplitudes were 0.1 and 0.2 times the free stream velocity.This research was funded by the Australian Government's Research Training Program (RTP) and by the Australian Government through the Australian Research Council (ARC DP-200101961)This data was published in the work by Hoang et al.

本数据集包含两组平板湍流边界层样本与八组带局部强迫的湍流边界层样本。两组平板湍流边界层的测量位置分别距前缘1239 mm与1295 mm；所有带局部强迫的湍流边界层样本的测量位置均距前缘1295 mm。所有测量均在来流速度固定为5.5 m/s、基于平板湍流边界层动量厚度θ的雷诺数Reθ≈1132的工况下完成。局部强迫频率分别为100、150、200与250 Hz，对应的无量纲频率依次为0.025、0.038、0.050及0.063；强迫振幅分别为来流速度的0.1倍与0.2倍。本研究受澳大利亚政府研究培训计划（Research Training Program, RTP）以及澳大利亚政府通过澳大利亚研究委员会（Australian Research Council, ARC DP-200101961）资助。本数据集相关成果发表于Hoang等人（2025）的研究中。Jafari, A., Cazzolato, B. 与Arjomandi, M.（2025）. 合成射流对湍流边界层近壁区猝发事件的调控. 国际热与流体流动杂志（International Journal of Heat and Fluid Flow）, 112, 109728. https://doi.org/10.1016/j.ijheatfluidflow.2024.109728
