| Abstract: | Reynolds Stress Model and Particle Trajectory Model were adopted to enumerate gas-solid two-phase flow field in the impeller of a centrifugal fan, meanwhile the research predicted erosion quotiety of blades visually based on Tabakoff and Grant Erosion Model. It is found that working surfaces of blades , front shell and back shell of the impeller all have their different erosion features. It was analysed that different diameters particles have their owner erosion modes to the working surfaces. According to the results pertinence abrasion resistant measures are provided. |
| Keywords: | gas-solid two-phase flow reynolds stress model erosion quotiety numerical simulation |
