摘 要:

提出一種基于圖像處理和模式聚類的二次仿真方法。應(yīng)用Fluent商業(yè)軟件對回轉(zhuǎn)窯內(nèi)粉煤在27類設(shè)定工況的燃燒進行溫度場的三維數(shù)值模擬,將仿真結(jié)果構(gòu)建仿真結(jié)果數(shù)據(jù)庫;采用模式聚類的方法判斷實際工況屬于哪一類標準工況,調(diào)用仿真結(jié)果數(shù)據(jù)庫建立溫度與該類標準工況的數(shù)學(xué)模型,求解模型并計算實際工況下的溫度場;利用圖像處理中的偽彩色變換得到二次仿真結(jié)果,用VC++6.0來實現(xiàn)。結(jié)果表明:該方法能夠較準確地給出仿真結(jié)果,極大縮短計算時間,為回轉(zhuǎn)窯內(nèi)溫度監(jiān)測提供一種新思路,具有較大的現(xiàn)場應(yīng)用價值,并很容易推廣到其他領(lǐng)域中。

Abstract:A secondary simulation method based on pattern recognition and image process was proposed. First, 3 dimensional numerical simulation of the powered coal combustion in rotary kiln was made under the 27 setting states by Fluent software, and the simulation results were constructed into a database; then, decide which class the actual state belongs to through pattern recognitions, get the simulation result of this class from database and build the mathematical model between the simulation result and input parameter, resolve the model and calculate the actual simulation result; at last, achieve the graphical simulation result by image process. The interface is realized using VC++6.0 program language. The experiments show that this method can get satisfactory simulation result in very short time, which provides a new way for the temperature inspection of rotary kiln and can be easily expanded to other field.

 

Key words: secondary simulation; pattern recognition; image process; Fluent numerical simulation; rotary kiln
