Phase response of the cross-talk area in can-annular combustors for different gap geometries

Can-annular combustors exhibit a small gap in front of the turbine that allows acoustic communication between neighbouring cans. The dataset contains the equivalent reflection coefficients obtained with FEM Helmholtz simulations performed with COMSOL Multiphysics. For each azimuthal order, and for each geometrical configuration, the absolute value and the phase response of the gap is given as a function of frequency.环管型燃烧室（can-annular combustors）的涡轮前设有微小间隙，可实现相邻燃烧室筒之间的声学连通。本数据集包含通过COMSOL Multiphysics开展有限元亥姆霍兹（FEM Helmholtz）模拟所得到的等效反射系数。针对每一种方位阶数与每一种几何构型，本数据集均给出了该间隙的幅值与相位响应随频率的变化关系。
