|
摘要
为提高涡轮叶片的数值计算效率,开发出基于参数控制的涡轮叶片模型软件。可实现叶片模型重构、计算域分区、结构化网格生成过程的自动完成和参数化控制,使得叶片的造型和网格生成过程简单化;对生成网格进行数值模拟计算,计算结果表明:生成网格在满足叶片数值计算精度的前提下,工作量大大减少,网格生成效率极大提高;在模型调整时,只需更改相应参数即可快速更新模型,缩短模型的生成周期,提高设计工作的可重用性。
In order to improve numerical efficiency of turbine blade computation, the model software of turbine blade based on parameter control was developed, the software can achieve the function of the modeling, the division of computational domain and the structured grid generation automatically, which will simplify the blade design greatly. The mesh file that is generated automatically can be applied to numerical simulation. The result shows that the software can reduce labor operation without any loss in the precision of blade numerical computation which improves the grid-generation efficiency greatly. The model can be rebuilt quickly only by changing the corresponding parameters, which can shorten the blade design period and increase reutilization of blade design.
