大泵流道CAD方法与技术研究
|
摘要
大型泵站中流道设计是整个泵站工程设计的关键,设计得好坏直接影响其可观的经济效益和社会效益。泵站工程中流道的研究目前大多集中在模型试验方面,理论研究主要在流道内部三维流动的理论和计算方法上,而流道CAD方法与技术的研究相对较少,基于CFD的流道流场模拟、可视化方法与实现的研究刚刚起步。随着泵站工程和CAD技术的迅速发展,人们对流道CAD系统提出了更高的要求。
本文基于Auto CAD开发平台,在新的开发环境ObjectARX支持下,采用面向对象的可视化编程工具Visual C++6.0研究泵站进出水流道CAD方法与技术。
本论文着重将先进的CAD方法与技术应用到泵站流道的设计中,重点内容主要包括两个部分:
(1)利用先进的CAD方法和技术升级、扩充原流道CAD功能,并对涉及到的CAD方法和主要实现技术进行研究。
(2)对基于流道CFD三维数值计算的流场可视化和模拟方法作进一步的探索。
本文主要创新点:
(1)将先进的CAD技术与方法进一步引入到泵站流道设计中,使其设计更具科学性,先进性和高效率等;
(2)对流道CAD设计方法作了有益探索,如基于ARX实体驱动的参数化方法实现及从三维到二维的流道CAD设计方法等;
(3)对流道三维造型的方法等作了较为深入地研究;
(4)对流道设计中一些数学模型问题,如肘形弯曲段的数模分析与应用、过渡圆角的变化规律等作了一些探索;
(5)继续探索了基于流道CFD三维计算流场的可视化和模拟方法与实现技术等。
Passageways design is the key design of the whole project in the large pump station, the results of which will directly affect its considerable economic efficiency and the social efficiency. At present, researches on the passageways of pump station are mostly focus on the model trail, and theoretical researches are mainly in the interior three-dimensional flow theory and computational method. Researches on the CAD method and technology in the design of the passageways of pump station are relatively very few at present, and researches on the simulation of flow fields, the method and realization of visualization based on CFD of passageways are just started. With the development of pump station and CAD technology, people set a higher request to the CAD system of the passageways.
Based on the development platform of AutoCAD, with the supporting of Object ARX, this paper researches the CAD method and technology in the design of the passageways of pump station, by adopting the object-oriented programming tool of Visual C++6.0.
This paper emphatically applies the advanced CAD method and technology into the design of passageways of pump station. Two main contents are included:
(1)Using the advanced CAD method and technology, improve and expand the original passageways CAD function, and discuss the CAD method and the realization technology which relate to.
(2)Further explore the visualization of 3D computational flow fields and the simulated method and technology based on passageways CFD of pump station.
The main creations of this paper:
(1)Introduce the advanced CAD method and technology into the design of the passageways of pump station, making the design have the scientificalness, the sophistication and high efficiency, and so on.
(2)Make some useful explorations to the passageways CAD design method, e.g the method of parametric design based on ARX entity objects driving and the method of passageways design from three-dimension to two-dimension and so on.
(3)Study the three-dimensional modeling deeply during the design of passageways.
(4)Make some explorations to the mathematical model during the design of passageways, e.g the analysis and application of the mathematical model in the elbow passageways curving section, the change rules of transition fillet, and so on.
(5)Continue to explore the visualization and simulation method and the realization technology based on 3D computational flow fields in passageways CFD.
