| 摘 要： | 叶轮机的叶型设计最终将决定叶轮机的性能,进行可视化的叶型设计,有利于有针对性地直接实施叶型局部优化,提高优化效率.本文基于Bezier理论,利用OpenGL作为图形图像的开发工具,开发了一套对叶轮机二维叶型进行可视化设计的软件,经优化设计前后的数值模拟比较,修型后的叶栅总压损失系数明显下降.表明该软件可以直观有效地应用于叶轮机设计.

| Abstract: | The profile design is one of the key tasks in the design of turbomachinery.Visualized design of the profile was propitious to realize the local blade optimum directly and efficiently.Based on Bezier theory,here a visualized software using Open GL API as graphic development tool was developed for 2D blade profile optimization.The comparison between the numerical results of pre-design and post-design shows that the stagnation pressure loss coefficient of modified airfoil is significantly decreased.It is indicated that the software can be effectively applied to turbomachinery design. |
