摘要
模拟高性能航空发动机涡轮叶片弦中区冷却结构 ,建立冲击粗糙复合冷却实验模型。通过对大量实验数据的分析和整理 ,建立了换热准则关系式。与实验结果对比表明 :该准则关系式与实验实测数据吻合较好 ,精度较高 。
The process of impingement heat transfer is quite complicated , especially when the target surface is rib roughened Based on thousands of experimental data in different parameter matching conditions, the correlation of the impingement heat transfer characteristics was analyzed The correlation equation of impingement heat transfer characteristics to the parameters was finally concluded Comparison shows that the correlation results are in good agreement with the experimental data
