Centrifugal fans having backward-curved blades are widely used in the various industrial fields because of their high efficiency and pressure characteristics. Performance measurement of a industrial centrifugal fan with a large scale needs high cost and time.
Numerical simulation is very effective to predict the performance of the fan. The accuracy of the numerical simulation on the fan still needs to enhance the degree of the accuracy. In the present study, a computational investigation was carried out to predict fan performance in the 200 kW scale industrial centrifugal fan. In the steady state numerical simulation, selection of a proper boundary condition is important to analyze the fan performance accurately.
Frozen-rotor and stage interface are introduced to compare the fan performance according to the relative positions between a cut-off of a volute casing and a impeller blade. It was found that the fan efficiency changes maximum 2% to the mean value according to the relative positions between a cut-off of a volute casing and a impeller blade. Detailed fan performance and internal flow fields are introduced and analyzed.
