模糊模式识别在流型判别中的应用

The Application of Fuzzy Pattern Recognization on Judging Flow Regimes

介绍了流型分类,提出了描述流型的特征参数,根据特征参数分别建立了判断段塞流的隶属度函数,并综合多种参数进行流型识别。将试验得到的数据代回评判流型的隶属度公式进行回判,结果表明,在一定的粘度范围内,应用模糊模式识别技术进行流型判别效果很好。

This article introduces classification of flow regimes and presents feature parameters for describing flow regimes. Subjection functions are constructed respectively according to feature parameters. Flow pattern recognization can be completed by colligating feature parameters. To evaluate the effects,the data obtained from experiments is repeatly applied in subjection function formula of judging flow regimes. The results show that sound effects can be obtained by application of fuzzy pattern recognization technique in judging flow regimes in a certain viscosity limit.
