摘要
采用Num eca的FINE/Turbo分析软件对4种原始叶型及其优化叶型进行了三维数值模拟,并对在不同马赫数与不同冲角下的气动性能作了比较。
By using the FINE/Turbo analysis software of Numeca, the present paper numerical simulates the four original and their optimum blade profiles with three-dimensional computation, and compares the aerodynamic characteristics with different Mach numbers and different incidences.
