提出一种嵌入式 H型网格技术 ,用于生成孤立翼型和叶栅的计算网格。与传统的 H型网格相比 ,采用嵌入式 H型网格时 ,翼型头部及尾部附近的网格畸变很容易得到控制 ,有益于提高计算的准确性。本文对两个孤立翼型在不同冲角下的流场进行了数值分析 ,采用嵌入式

An embedded H grid technique is employed for generating grids of isolated airfoils and cascades.Comparing with original H grid,the embedded H grid is easy to control the orthogonality of grids around the leading and trailing edges of airfoils and useful to improving the accuracy of computation.Two numerical analyses of isolated airfoils under different incidences show that the results of computation using the embedded H grid are in good agreement with experimental data.
