 In this study,   energy performance of a new flat plate solar
air collector (SAHs) with different obstacles at fin shape and rectangle Type I
and  Type II was
investigated. The measured parameters were the inlet and outlet temperatures,
the absorbing plate temperatures, the ambient temperature, and the solar
radiation. Further, the measurements were performed at
different values of mass flow rate of air (0.0074, 0.0052, 0.0016 kg/s). The thermal efficiency was calculated based on the measurements The
results obtained were trained and tested with the support vector machine (SVM) which
is one of the regression analyse methods. 10-fold cross-validation method
was used to evaluate the regression performance. The best regression
analysis result was obtained using cubic SVM method in which R² was
0.88 in the Type II air collector. Comparison
between predicted and experimental results indicates that the proposed SVM
model can be used for estimating the efficiency of SAHs with reasonable
accuracy.
