【摘要】：抽水蓄能電站地下廠房空間較大,內(nèi)部設(shè)備布置復(fù)雜,存在較大的發(fā)熱量,且廠房內(nèi)氣流組織形式較為復(fù)雜,其溫濕度科學(xué)設(shè)計問題顯得更加突出。計算流體動力學(xué)(CFD)軟件對氣流組織進行數(shù)值模擬分析具有成本低、周期短、靈活性強等優(yōu)點,在暖通空調(diào)專業(yè)的應(yīng)用也越來越廣泛。但是,CFD軟件學(xué)習(xí)操作過程相對比較復(fù)雜,對工程師而言熟練進行氣流組織模擬計算需花費大量時間和精力。有鑒于此,開發(fā)出一個能夠?qū)崿F(xiàn)快速、簡單進行自動參數(shù)化建模和模擬計算、并具有較高工程精度的軟件平臺是一項頗有工程意義的任務(wù)。 本課題是基于中國水電顧問集團華東勘測設(shè)計研究院有限公司委托的“抽水蓄能電站地下廠房空氣調(diào)節(jié)動態(tài)模擬軟件平臺開發(fā)”項目,由西安建筑科技大學(xué)李安桂教授課題組研究完成。項目主要包括軟件平臺開發(fā)和2D-PIV試驗驗證兩部分組成,課題組成員陶鵬飛主要對數(shù)值模擬邊界條件和試驗驗證的內(nèi)容進行了研究,本文主要描述的則是仿真平臺開發(fā)過程算法和母線層氣流組織對比分析。 該數(shù)值模擬平臺能夠自動調(diào)用Gambit口Fluent軟件,讀取對應(yīng)的腳本文件,實現(xiàn)參數(shù)化建模、計算網(wǎng)格自動生成、自動數(shù)值計算、后處理展示計算結(jié)果等。在VC++6.0平臺中對軟件平臺后續(xù)封裝,考慮到人機界面的交互性,設(shè)計出適合操作人員使用的界面形式。將計算結(jié)果與試驗數(shù)據(jù)進行對比,驗證平臺計算結(jié)果的可靠性。 利用該程序計算了母線層三種不同送風(fēng)方案下氣流組織效果,通過速度不均勻系數(shù)和溫度不均勻系數(shù)進行比較了各種方案的特點。基于該平臺,可以方便快速的實現(xiàn)電站廠房內(nèi)的氣流組織計算,為氣流組織方案設(shè)計提供了一種簡單、實用的計算工具。
[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.
