H2020 ENODISE: Numerical Aeroacoustic Database Configuration A1 : GPUP

This dataset contains the numerical prediction for A1 configuration as defined in the H2020 ENODISE project (https://www.vki.ac.be/index.php/about-enodise). In this configuration, a single two-bladed propeller is immersed in a boundary layer. The present results can be compared to the measurements carried out by the University of Bristol. The investigated operating point as calculated in the prediction is: Uinf = 33 m/s, 6500 rpm, advance ratio J=1 The results were calculated using the LES-CABARET method on GPUs. The results presented are preliminary result on coarse grid with the comparison with the experiment for hot-wire and overhead acoustic data at 60-, 90- and 120-degree observer angles.本数据集包含H2020 ENODISE项目（https://www.vki.ac.be/index.php/about-enodise）所定义的A1构型的数值预测结果。该构型中，单个双叶片螺旋桨浸没于边界层流场之中。本次所得结果可与布里斯托大学开展的实测数据进行对标分析。本次预测采用的研究工况为：来流速度Uinf=33 m/s、转速6500 rpm、进速比J=1。本研究采用基于图形处理器（Graphics Processing Unit, GPU）的大涡模拟（Large Eddy Simulation, LES）-CABARET方法完成数值计算。本次展示的结果为粗网格下的初步计算结果，包含针对60°、90°及120°观测角下的热线风速仪与顶面声学测量数据的实验对比。
