| Abstract |
CFD analysis shows that if the inlet of a cyclone type oil separator is eccentric; the pressure drop can be reduced while increasing the separation efficiency. It has also been shown that the application of oleophilic surfaces can lead to higher separation efficiency but lead to increased pressure drop. In the present study, an oil separator with an eccentric inlet was fabricated and the CFD prediction results tested through performance evaluation in the actual refrigeration cycle. When the inlet of the cyclone type oil separator is eccentric, the improvement in the separation efficiency was not significant compared with the result predicted using numerical analysis, but the pressure drop was greatly reduced. In conclusion, the pressure loss is greatly reduced when the inlet is eccentric. The separation efficiency was enhanced by about 15% with a 30% reduction in pressure drop with the application of an olephilic surface treatment on the geometry. |
