摘要
The factors which affect the oil film formation when the oil mist is spraying against the metal plate were studied via a numerical simulation with the software FLUENT, then the contour maps of oil film thickness were plotted. In the simulation the spray speeds were 30, 80, 100 and 120 m/s; the oil drop sizes were 3, 5, 7 and 10 μm; and the spraying distances were 50 and 65 mm. The results showed that the oil film thickness and film forming ratio both decrease with increasing spraying distance, and both are comparatively perfect when the spraying distance is 50 mm with the spray speed 80 m/s. Meanwhile, both become bigger when the oil drop size is about 5 μm.
