Abstract

Abstract:

The internal flow field of an inertial particle separator model is tested by the technology of particle image velocimetry (PIV), and the structure characteristics of the flow field is analyzed. According to the experimental results, an obvious separated flow can be found near the entrance of the scavenge flow path along different heights, and the behaves differently with different parameter scavenge core ratio (SCR,14% to 20%) and inlet flow rate. The existence of the separated flow is one of the reasons that result the low separation efficiency of the small size particles. Experimental results show that the solid wall has great influence on the scale of the separated flow, and the closer to the wall, the bigger the backflow vortex is. When the SCR increases, the scale of the separated flow gets smaller. With the increase of the inlet flow rate, there is little change of separated flow scale. It is shown that the internal fluid field and the separated flow scale are mainly determined by the SCR parameter. The results can provide reference for the numerical simulation and improvement of the separator structure.
