H2020 Enodise: Analytical dataset configuration B2 ECL

This dataset considers analytical data for configuration B2 as defined in the H2020 ENODISE project (https://www.vki.ac.be/index.php/about-enodise). The results were calculated using the half-plane Green's function for the convected Helmholtz equation for predicting the sound scattering by trailing edges in the presence of a uniform flow. For mimicking the Distributed Electric Propulsion (DEP) configuration model which includes a wing and two side-by-side propellers measured during the wind tunnel tests, the formalism of source-modes is introduced, from which the sound field could be expressed uniformly in the whole space. The wing was approximated by a thin plate with zero-thickness. The aerodynamic performance of the propeller was calculated by using a BEMT method.本数据集涵盖了H2020 ENODISE项目（https://www.vki.ac.be/index.php/about-enodise）中定义的配置B2的分析数据。相关结果基于对流波动亥姆霍兹方程（convected Helmholtz equation）的半平面格林函数（half-plane Green's function）计算得到，用于预测均匀流场环境下尾缘的声波散射特性。为模拟风洞试验中测得的包含机翼与两台并列螺旋桨的分布式电推进（Distributed Electric Propulsion, DEP）构型模型，本研究引入了源模态（source-modes）形式体系，借此可在全空间内统一表述声场。研究中将机翼近似为零厚度薄板，螺旋桨的气动性能则通过叶素动量理论（Blade Element Momentum Theory, BEMT）方法计算得到。
