Comparison of Methodologies for the Detection of Multiple Failures Using Acoustic Images in Fan Matrices
Table 3
SVM accuracy rates of the individual faulty fan detection methodology with two faulty fans working situation of the matrix.
| Individual faulty fan detection methodology: two faulty fans tests | Accuracy rate (%) |
| Global | | 87.9 | Two faulty fans separation | | | Case A: horizontal/vertical step distance (no central fan) | | 89.5 | Case B: horizontal/vertical step distance (with central fan) | | 89.3 | Case C: diagonal step distance | | 84.3 | Case D: knight movement distance | | 89.6 | Case E: row/column distance | | 84.7 | Case F: diagonal distance | | 92.5 |
