摘要

增材制造技术可以制造出相对复杂的冷却结构,如三重周期性最小表面(TPMS),从而实现单位体积的高热传导。本研究展示了金刚石-TPMS 拓扑结构在燃气轮机叶片后缘通道中的紊流传热和热应力。在近乎真实的燃气轮机工况下,对由定向凝固 GTD111 制成的 Diamond-TPMS 结构进行了热-流-固分析,并将分析结果与雷诺数为 30,000 的传统针翅阵列进行了比较。与基线针翅结构相比,Diamond-TPMS 模型使整个通道的流动特性分布更加均匀。整体传热增强、摩擦因数比和热性能分别提高了 145.3%、200.9% 和 32.5%。Diamond-TPMS 模型中的温度、位移和热应力分布也更加均匀。金刚石-TPMS 模型外表面的平均温度比基准针翅阵列低 19.9%。楔形冷却通道中的金刚石-TPMS 网络有助于将材料热膨胀引起的体积位移减少 29.3%。此外,Diamond-TPMS 结构中的体积平均 von Mises 应力降低了 28.8%。

Turbulent Flow Heat Transfer and Thermal Stress Improvement of Gas Turbine Blade Trailing Edge Cooling with Diamond-Type TPMS Structure
Additive manufacturing allows the fabrication of relatively complex cooling structures, such as triply periodic minimal surface (TPMS), which offers high heat transfer per unit volume. This study shows the turbulent flow heat transfer and thermal stress of the Diamond-TPMS topology in the gas turbine blade trailing edge channel. The thermal-fluid-solid analysis of the Diamond-TPMS structure, made of directionally solidified GTD111, at the nearly realistic gas turbine condition is executed, and the results are compared with the conventional pin fin array at the Reynolds number of 30,000. Compared to the baseline pin fin structure, the Diamond-TPMS model distributes flow characteristics more uniformly throughout the channel. The overall heat transfer enhancement, friction factor ratio, and thermal performance are increased by 145.3%, 200.9%, and 32.5%, respectively. The temperature, displacement, and thermal stress in the Diamond-TPMS model are also distributed more evenly. The average temperature on the external surface in the Diamond-TPMS model is lower than the baseline pin fin array by 19.9%. The Diamond-TPMS network in the wedge-shaped cooling channel helps reduce the volume displacement due to the material thermal expansion by 29.3%. Moreover, the volume-averaged von Mises stress in the Diamond-TPMS structure is decreased by 28.8%.
