激波风洞（FD-14/FD-14A）边界层转捩实验数据

本数据集包含一系列在激波风洞（FD-14/FD-14A）中进行的高超声速边界层转捩实验的热流数据、脉动压力数据、纹影图片。辅助性材料包括：模型测点分布以及风洞的运行工况。数据集主要用以对高超声速流动中转捩进行判据以及分析边界层转捩过程中不稳定波的演化。实验数据包括圆锥边界层转捩过程中热流数据、脉动压力数据和纹影图片。圆锥构型边界层实验数据包含不同来流工况（马赫数，单位雷诺数，攻角）和不同钝度前缘半径和不同波纹壁的模型。在风洞有效运行时间内，壁面热流数据通过薄膜传感器采集得到温度随时间的信号，随后对温度进行积分得到时均热流。脉动压力数据通过PCB132 B38传感器采集得到压力随时间的信号而后对其进行频谱分析。壁面热流数据和脉动压力数据都具有较好的重复性。This dataset contains heat flux data, fluctuating pressure data, and schlieren images of hypersonic boundary layer transition experiments conducted in the shock tunnels FD-14/FD-14A. Supplementary materials include the distribution of model measuring points and the wind tunnel's operating conditions. This dataset is primarily intended for establishing transition criteria for hypersonic flows and analyzing the evolution of unstable waves during the boundary layer transition process. The experimental data encompasses heat flux data, fluctuating pressure data, and schlieren images acquired during the cone boundary layer transition process. The cone-configured boundary layer experimental dataset includes models with varying inflow parameters (Mach number, unit Reynolds number, angle of attack), different blunt leading edge radii, and models with distinct corrugated wall configurations. Within the effective operating duration of the wind tunnel, wall heat flux data was collected using thin-film sensors to capture temperature-time signals, and the time-averaged heat flux was subsequently calculated by integrating these temperature signals. Fluctuating pressure data was collected via PCB132 B38 sensors to obtain pressure-time signals, followed by spectral analysis performed on these signals. Both the wall heat flux data and fluctuating pressure data exhibit good repeatability.
