The prediction of wall factor of particle settling in rectangular ducts using Support Vector Machine

ABSTRACT: In order to characterize wall effect of rectangular ducts on settling particle, a prediction method of wall factor was presented using Support Vector Machine. Extracted ρ , ρs, dp, d/a, a/b, K and n as feature parameters, which affect particle settling velocity greatly. Culled 70 data of Machač to train and test the model, the results show that: Support Vector Machine sufficiently accurate in engineering applications, the error is less 5% for 90% calculated results and can be used in parallel plate and rectangular ducts case, the application range of Support Vector Machine are broader, which can meet complicated engineering applications.
