本文报道了在计算流体力学中的一个完全复制的研究,使用浸没边界方法获得俯仰和滚转椭圆机翼的绕流。与最初的研究一样,计算实验研究了尾流拓扑和气动力,考察了雷诺数(100--400)、斯特劳哈尔数(0.4--1.2)、展弦比和滚转/俯仰相位差的影响。我们还包括一个网格独立性的研究(从500万到7200万网格单元)。尽管结果存在一些差异,但空气动力学性能的趋势和尾流拓扑结构的特征得到了复制。我们宣布复制成功,并完全提供所有数字工件和工作流定义,包括软件构建配方和容器映像,以及辅助数据和后处理代码。每个计算实验的运行时间在8.1到13.8小时之间,以完成5个挥舞周期,使用两个计算节点,每个计算节点具有双20核3.7GHz Intel Xeon Gold 6148 CPU和两个NVIDIA V100 GPU设备。
This article reports on a full replication study in computational fluid dynamics, using an immersed boundary method to obtain the flow around a pitching and rolling elliptical wing. As in the original study, the computational experiments investigate the wake topology and aerodynamic forces, looking at the effect of: Reynolds number (100--400), Strouhal number (0.4--1.2), aspect ratio, and rolling/pitching phase difference. We also include a grid-independence study (from 5 to 72 million grid cells). The trends in aerodynamic performance and the characteristics of the wake topology were replicated, despite some differences in results. We declare the replication successful, and make fully available all the digital artifacts and workflow definitions, including software build recipes and container images, as well as secondary data and post-processing code. Run times for each computational experiment were between 8.1 and 13.8 hours to complete 5 flapping cycles, using two compute nodes with dual 20-core 3.7GHz Intel Xeon Gold 6148 CPUs and two NVIDIA V100 GPU devices each.
