摘要:

HIFiRE-5、HyTRV均为验证高超声速三维边界层转捩的典型标模。C-γ-Reθ 转捩模型在原始的γ-Reθ 转捩模型基础上进行了高超声速横流转捩修正。运用C-γ-Reθ 转捩模型对飞行、风洞工况下HIFiRE-5、HyTRV进行转捩模拟。对于HIFiRE-5飞行试验,针对其弹道中8个典型高度及存在姿态角的工况进行转捩预测,C-γ-Reθ 转捩模型计算结果与热流测量结果吻合,并对其表面的转捩模态进行了对比分析。对于HIFiRE-5静音/常规风洞试验,C-γ-Reθ 转捩模型能够准确计算变雷诺数工况下转捩阵面形态及转捩起始位置,并与温升测量结果相符。对于HyTRV常规风洞试验,在变马赫数、变雷诺数的工况下,C-γ-Reθ 转捩模型计算结果与模型上、下表面红外热图测量结果基本一致,能够预测横流模态下的边界层转捩,对于转捩起始位置、转捩阵面形态的预测与基于线性稳定性理论的e N 方法具有相当的预测精度。测试表明,对于飞行试验和静音/常规风洞试验,C-γ-Reθ 转捩模型预测结果均保持较高的可靠性,实现了高超声速典型标模的三维边界层转捩预测。

Abstract:

Standard models such as HIFiRE-5 and HyTRV are used in the validation of hypersonic three-dimensional boundary layer transition. Hypersonic crossflow transition correction is proposed in the C-γ-Reθ transition model based on the original γ-Reθ transition model. In this study, the C-γ-Reθ transition model is applied to transition simulation of HIFiRE-5 and HyTRV under flight test and wind tunnel test conditions. For the flight test of HIFiRE-5, transition prediction is conducted under the conditions including eight typical altitudes and one attitude angle, the results of the C-γ-Reθ transition model are consistent with the heat-flux measurements, and the transition modes on the surface of HIFiRE-5 are compared. For the quiet/noise wind tunnel test of HIFiRE-5, the C-γ-Reθ transition model can accurately calculate the transition front shape and the transition onset location, and the results coincide with the temperature difference measurements. For the noise wind tunnel test of HyTRV, the C-γ-Reθ transition model calculation results of the upper and lower surfaces match with the infrared thermogram measurements under the conditions involving various Reynolds numbers and Mach numbers, and the ability to predict boundary layer transition in the crossflow mode is verified. Its prediction precision of the transition onset location and the transition front shape is on par with the e N method based on LST. As shown in the numerical simulation results, for each of the flight test and the quiet/noise wind tunnel test, the C-γ-Reθ transition model maintains high prediction reliability, and has achieved hypersonic three-dimensional boundary layer transition prediction for typical standard models.
