使用 DLR TAU 流动求解器与雷诺应力模型相结合,研究了两种不同翼尖形状的涡卷卷过程。特此探讨 SSG/LRR-雷诺应力模型的性能。将模拟结果与最先进的涡粘模型以及文献和自己的研究的实验结果进行比较。 SSG/LRR 模型比涡粘模型更准确地预测平均流量。然而,可以发现与实验相比的偏差,这与内部涡核中雷诺应力的不准确预测有关。
Vortex roll-up processes at two different wing tip shapes are investigated using the DLR TAU flow solver in combination with a Reynolds Stress Model. The performance of the SSG/LRR-Reynolds Stress Model is hereby explored. Results from simulations are compared to state-of-the-art eddy-viscosity models as well as experimental results from literature and own investigations. The SSG/LRR-model predicts the mean flow much more accurately than the eddy-viscosity models. However, deviations up tocompared to experiments can be found which are related to an inaccurate prediction of the Reynolds stresses in the inner vortex core.
