基于实验结果 ,对中心进气和高位垂直进气转静系旋转盘的冷却品质进行了较为系统的比较 ,结果发现 :虽然两者的盘面平均努赛尔特数和无量纲过余体平均温度相差很小 ,但是从减小径向温差角度看 ,高位垂直进气具有明显的优势 ,证明了以前提出的涡轮盘冷却指标应包含径向温差的合理性。 Based on the experimental results, the cooling quality of the central inlet and the high vertical inlet rotating static and dynamic rotating disc are systematically compared. The results show that although both the average Nusselt number and the non-dimensional excess body average temperature However, from the point of view of reducing the radial temperature difference, the high vertical inlet air has obvious advantages. It proves that the previous proposed turbine disk cooling index should include the reasonable radial temperature difference.
