【摘要】：抽水蓄能电站地下厂房空间较大,内部设备布置复杂,存在较大的发热量,且厂房内气流组织形式较为复杂,其温湿度科学设计问题显得更加突出。计算流体动力学(CFD)软件对气流组织进行数值模拟分析具有成本低、周期短、灵活性强等优点,在暖通空调专业的应用也越来越广泛。但是,CFD软件学习操作过程相对比较复杂,对工程师而言熟练进行气流组织模拟计算需花费大量时间和精力。有鉴于此,开发出一个能够实现快速、简单进行自动参数化建模和模拟计算、并具有较高工程精度的软件平台是一项颇有工程意义的任务。 本课题是基于中国水电顾问集团华东勘测设计研究院有限公司委托的“抽水蓄能电站地下厂房空气调节动态模拟软件平台开发”项目,由西安建筑科技大学李安桂教授课题组研究完成。项目主要包括软件平台开发和2D-PIV试验验证两部分组成,课题组成员陶鹏飞主要对数值模拟边界条件和试验验证的内容进行了研究,本文主要描述的则是仿真平台开发过程算法和母线层气流组织对比分析。 该数值模拟平台能够自动调用Gambit口Fluent软件,读取对应的脚本文件,实现参数化建模、计算网格自动生成、自动数值计算、后处理展示计算结果等。在VC++6.0平台中对软件平台后续封装,考虑到人机界面的交互性,设计出适合操作人员使用的界面形式。将计算结果与试验数据进行对比,验证平台计算结果的可靠性。 利用该程序计算了母线层三种不同送风方案下气流组织效果,通过速度不均匀系数和温度不均匀系数进行比较了各种方案的特点。基于该平台,可以方便快速的实现电站厂房内的气流组织计算,为气流组织方案设计提供了一种简单、实用的计算工具。
[Abstract]:The space of underground powerhouse of pumped storage power station is large, the arrangement of internal equipment is complex, there is a large calorific value, and the form of air distribution in the plant is more complex, so the scientific design of temperature and humidity is more prominent. The numerical simulation analysis of airflow organization by computational fluid dynamics (CFD) software has the advantages of low cost, short cycle and strong flexibility, and is more and more widely used in HVAC specialty. However, the learning and operation process of CFD software is relatively complex, and it takes a lot of time and effort for engineers to carry out airflow organization simulation calculation skillfully. In view of this, it is of great engineering significance to develop a software platform which can realize fast, simple automatic parametric modeling and simulation calculation, and has high engineering accuracy. This project is based on the project "Development of dynamic Simulation Software platform for Air conditioning of Underground Workshop of pumped Storage Power Station" commissioned by China Hydropower Consulting Group, East China Survey and Design Research Institute Co., Ltd., which is studied by Professor Li Angui of Xi'an University of Architectural Science and Technology. The project mainly includes two parts: software platform development and 2D-PIV test verification. Tao Pengfei, a member of the research group, mainly studies the numerical simulation boundary conditions and the contents of experimental verification. This paper mainly describes the development process algorithm of the simulation platform and the comparative analysis of bus layer air flow organization. The numerical simulation platform can automatically call Gambit port Fluent software, read the corresponding script file, realize parametric modeling, automatic generation of computational grid, automatic numerical calculation, post-processing display of calculation results and so on. After encapsulating the software platform in VC 6.0, considering the interaction of man-machine interface, the interface form suitable for operators is designed. The calculated results are compared with the experimental data to verify the reliability of the calculated results of the platform. The air distribution effect under three different air supply schemes in the bus layer is calculated by using this program, and the characteristics of each scheme are compared by the velocity inhomogeneity coefficient and the temperature inhomogeneity coefficient. Based on this platform, the calculation of air distribution in power plant can be realized conveniently and quickly, which provides a simple and practical calculation tool for the design of air distribution scheme.
