摘要

应用数值模拟来准确预测装有高升力装置的飞机的失速行为具有挑战性。使用雷诺平均纳维斯托克斯(RANS)模型进行模拟,在高攻角、边界层分离和重新连接的情况下缺乏可靠性,而对高雷诺数下壁界流动进行壁面分辨大涡流模拟(LES)目前则耗费了过多的计算资源。本研究提出了一种新的统一混合湍流建模方法,即自适应湍流涡模拟(SATES),并将其与加权紧凑非线性方案(WCNS)的高阶数值方案相结合,应用于复杂湍流。它实现了从非稳态 RANS 到 LES 的无缝演化,并最终根据湍流尺度接近直接数值模拟(DNS)。在 SATES 框架内,通过基于增强的子网格尺度 σ 模型扩展底层 LES 模式,开发了具有自适应模型系数的新 SATES-σ 模型。新的 SATES-σ 模型首先在通道流和流过方形圆柱体的两种基准情况下进行了检验。然后,在经过圆柱体的超临界流中对其进行验证,以评估湍流模型的性能。结果表明,与之前的 SATES 和 IDDES 相比,在边界层流动预测方面有了明显改善。最后,在精确预测 MD-30P30N 机翼在雷诺数为 9×106 时的大迎角失速方面取得了成功应用。模拟结果表明,即使在攻角为 21 度和 23 度的高难度情况下,表面压力与实验结果也非常吻合。同样,SATES-σ 也显示出比以前的 SATES 和 IDDES 更好的结果。所提出的方法对于具有挑战性的失速预测具有相当大的潜力。

Improved self-adaptive turbulence eddy simulation for complex flows and stall prediction using high-order schemes

It is challenging to apply numerical simulations to accurately predict the stall behavior of aircraft equipped with high-lift devices. Simulations with Reynolds-Averaged NavierStokes (RANS) models suffer from lack of the reliability at high angles of attack with separated and reattached boundary layers, whereas wall-resolved Large Eddy Simulations (LES) of wall-bounded flows at high Reynolds numbers currently costs too much computational resources. A new unified hybrid turbulence modeling approach, denoted the Self-Adaptive Turbulence Eddy Simulation (SATES), is proposed and applied for complex turbulent flows combining with high-order numerical scheme of the Weighted Compact Nonlinear Scheme (WCNS) in the present study. It enables a seamless evolution from unsteady RANS to LES and finally approaches Direct Numerical Simulation (DNS) depending on the turbulent scales. In the framework of SATES, a new SATES-σ model with an adaptive model coefficient is developed by extending the underlying LES mode based on an enhanced sub-grid-scale model of the σ-model. The new SATES-σ is first examined in two benchmark cases of channel flow and flow past a square cylinder. Then, it is validated in supercritical flow past a circular cylinder to assess the performance of turbulent models. The results show significant improvements over the previous SATES and IDDES in the predictions of boundary layer flow. Finally, successful application is achieved in the accurate prediction of the stall of the MD-30P30N airfoil at a Reynolds number of 9×106 with wide angles of attack. The simulation results show good agreement with experimental results for surface pressure even for the challenging cases of 21 and 23 deg angles of attack. Again, the SATES-σ shows better results than the previous SATES and IDDES. The presented method has considerable potential for the challenging stall predictions.

期刊介绍: The European Journal of Mechanics - B/Fluids publishes papers in all fields of fluid mechanics. Although investigations in well-established areas are within the scope of the journal, recent developments and innovative ideas are particularly welcome. Theoretical, computational and experimental papers are equally welcome. Mathematical methods, be they deterministic or stochastic, analytical or numerical, will be accepted provided they serve to clarify some identifiable problems in fluid mechanics, and provided the significance of results is explained. Similarly, experimental papers must add physical insight in to the understanding of fluid mechanics.
