Abstract:

A fouling test system was set up and the least squares-support vector machine for regression (LS-SVMR)was built to predict the fouling characteristics of the plain tube,with input vectors of tube wall temperature, inlet and outlet temperatures and output vector of fouling resistance.The model was proved to be reasonable and feasible by comparing predictions and measurement results.The results showed that the model is applicable not only to the conditions that water flow, ambient temperature, and material parameters are constant, but also to the conditions when they change.
