Energy conservation and and reformation of power plants " heat installation affect a lot on the efficient performance of opertion of power plant. pump and fan take a large proportion in power plant and resume much electric energy. so there is much energy conservation pationlity in them. and we should have strong tools and theories " support to reform them. we can combine the theory modeling and engineering design manufacture by the bussiness software such as fluent. in order to take full advantage of the powerful function of fluent and increase absolutely its conveniece and interaction, we should develop fluent secondly. this paper puts the idea firstly demostricly to substitute the performance test of pump and fan to get the integrative system of the optimization and computer aid design, and so we can increase greatly of the efficiecy and quality of the facility reformation. the main idea about the secondary development of fluent in this paper is based on the secondary development of gambit, the modeling and meshing s oftware of fluent, and simplify the modeling and meshing of gambit. meanwile, the data management base on web browser kind is adopted for the convenience of optimization and parameterization, and the journal files createdly recently can get new medeling and meshing files that can be used by fluent. so the designer can focus on the computer scheme and the result analysis without care the fussy designing and optimiziation. so we can increase greatly the optimization efficiency
泵與風機在電廠中占較大數量比例，且消耗大量電能，節能潛力巨大，對其改造需要強有力的工具和理論支持，用商用cfd軟體如fluent可實現泵與風機改造中的理論模擬與工程設計製造間的結合。為了充分發揮fluent的強大功能，又能最大程度地提高其方便性與交戶性，應對其進行二次開發。本課題在國內首先提出對fluent進行二次開發，替代泵與風機性能試驗，形成一體化的優化、輔助製造系統，可大大提高設備改造的效率與質量，其主要思想是基於fluent的cad構體軟體gambit進行二次開發，簡化了泵的構體過程，同時，為了優化及參數化方便，採用基於webbrowser的數據管理方式，生成新的記錄文件同時產生新的fluent計算能識別的圖形網格文件，這樣就將設計優化者從繁瑣的圖形設計及優化中解脫出來，專注于對計算方案的確定及計算結果的分析，極大地提高了設計優化的效率。 -
