Abstract

Gas turbine blade icing is a significant issue that poses a serious threat to the safe operation of the equipment. Current research on three-dimensional blade icing has limitations that hinder the advancement of icing mechanisms and gas turbine design theories. This study combines a traditional wind tunnel with a low-temperature natural environment to obtain experimental data on the icing characteristics of three-dimensional compressor inlet guide vanes. A comparative analysis was conducted to examine the effects of environmental temperature and liquid water content on the blade icing shape, icing area, icing thickness, and icing limits. The experimental results show that ice accretion on the blades mainly concentrates on the leading edge, trailing edge, and pressure side. And the blade icing exhibits significant three-dimensional characteristics. In the spanwise direction, the total icing area rate of the blade exhibits a high-middle and low-end characteristic. In the chordwise direction, the icing thickness exhibits a trend of being thicker at the leading edge, gradually thinning along the pressure side, and increasing again at the trailing edge. When liquid water content is 2.75 g/m³, the maximum total icing area rate increases by approximately 114.05 % as the temperature decreases from −5.5 °C to −9.5 °C. When the temperature is −3°C, the maximum total icing area rate increases by approximately 9.41 % as liquid water content rises from 0.63 g/m³ to 0.99 g/m³. The research results can provide an experimental foundation for further studies on the icing mechanisms and anti-icing methods of compressor inlet guide vanes.

低温大气环境下压气机叶片三维结冰特性实验研究

燃气轮机叶片结冰是燃气轮机的一个重要问题，严重威胁着燃气轮机的安全运行。目前对叶片三维结冰的研究存在局限性，阻碍了结冰机理和燃气轮机设计理论的发展。本研究将传统风洞与低温自然环境相结合，获得三维压气机进气道导叶结冰特性的实验数据。对比分析了环境温度和液态水含量对叶片结冰形状、结冰面积、结冰厚度和结冰极限的影响。实验结果表明，叶片上的冰积主要集中在前缘、尾缘和压力侧。叶片结冰具有明显的三维特征。在展向上，叶片总结冰面积率呈现出高、中、低端的特征。在弦向方向上，结冰厚度呈现前缘变厚，沿压力侧逐渐变薄，尾缘再次增大的趋势。当液态水含量为2.75 g/m3时，当温度从- 5.5℃降低到- 9.5℃时，最大总结冰面积率增加了约114.05%。当温度为−3℃时，随着液态水含量从0.63 g/m3增加到0.99 g/m3，最大总结冰面积率增加了约9.41%。研究结果可为进一步研究压气机进气道导叶结冰机理和防结冰方法提供实验基础。
