Research Abstract

The phenomena caused by the stall of turbo machinery is greatly different between fan and compressor. In case of compressor, surge phenomena with large pressure oscillation occur and the avoidance of it is very important issue. In this research, the effect of rotational speed on surge phenomena is investigated experimentally by using compressor of turbo charger.
As rotational speed is increased, it became clear that the surge region expands rapidly and it further expands abruptly above 50000rpm.
The effect of tank volume and pipe length is also tested and found that they have large influence on surge phenomena. Especially surge is proved to be extinguished at shorter pipe length of 2.0m under 20000 rpm operation.
