B. Comparison of LS-SVM Model with Traditional Models
Three traditional empirical models are adopted to predict
the flooding velocity of DN50 plastic short-cascade ring,
DN50 metal Pall ring and DN38 metal Intalox saddle. Then,
they are used to make the comparison with the LS-SVM
model. The first correlation is the Bain-Hougein equation
[14,15], which is an improvement and regression of the
Sherwood chart, formulated in (16):
