H2020 ENODISE: SISW Numerical Aeroacoustic Database Configuration B2

This database contains the aeroacoustic numerical results generated by Siemens Industry Software (SISW) for the B2 configuration investigated in the framework of the European project ENODISE. In this configuration, a six-blade propeller mounted on a support is studied for two operating points with and without flow. The operating points correspond to conditions 65 and 66 of the experimental campaign carried out at Ecole Centrale of Lyon (see H2020 Enodise: Experimental dataset configuration B2 ECL, https://zenodo.org/record/7925336). The two investigated operating points are: Uinf = 0 studied numerically using detached-eddy simulation combined with finite-element method for acoustics Uinf = 22 m/s studied numerically using large-eddy simulation combined with finite-element method for acoustics The SISW aeroacoustic results have been obtained using CFD software Simcenter STAR-CCM+ coupled with acoustic software Simcenter 3D Acoustics. The hydrodynamic and acoustic interactions between the propeller and its support are taken into account in the numerical simulations. More information about the numerical setup and results can be found in the documentation included in the database. The data are saved in dat files.本数据库收录了西门子工业软件（Siemens Industry Software，SISW）针对欧洲项目ENODISE框架下研究的B2构型生成的气动声学数值结果。该构型以安装于支架上的六叶螺旋桨为研究对象，设置了有来流与无来流两种工况。此二工况对应里昂中央理工学院开展的实验测试中的工况65与66（详见H2020 Enodise: Experimental dataset configuration B2 ECL，https://zenodo.org/record/7925336）。本次研究的两种工况分别为：来流速度Uinf=0，采用分离涡模拟（detached-eddy simulation）结合声学有限元法开展数值计算；来流速度Uinf=22 m/s，采用大涡模拟（large-eddy simulation）结合声学有限元法开展数值计算。本数据集的气动声学结果通过CFD软件Simcenter STAR-CCM+与声学软件Simcenter 3D Acoustics耦合计算得到。数值模拟过程中已充分考虑螺旋桨与其支架之间的水动力与声学相互作用。数据库附带的文档中包含更多关于数值设置与计算结果的详细信息。所有数据均以dat文件格式存储。
