Abstract

In order to optimize the rotating angle of the auto louver, the air-cleaner with turbo fan was numerical and experimentally analyzed . The noise generated from the auto louver was changed by modifying the installation angle of the louver. Flow field and flow noise were analyzed numerically by commercial tool SC/Tetra and FlowNoise S/W. Experiment was also done at anechoic chamber. From the numerical and experimental data, we can find the optimal rotating angle for auto louver of the air-cleaner.
