Summary: | The concentration precision of the sand/dust test and the attrition of key parts are affected seriously by the inertia efficiency separator, so the study on the separator performance is needed in the design of the sand/dust test system. With the application of discrete phase model, the performances of the manifold inertia separation components are simulated in various air velocities. The trajectories of motion of the particles in the separator are obtained, and the main factors which affect the separation efficiency are analyzed separately. According to the numerical simulation results, three types of separation components are designed and used in the experiment study, the results of the experiment study and the numerical simulation are consistent. The study results indicated that the increase of the particle dynamic energy is the main cause which leads to the separation efficiency drop rapidly while the air velocity increases. The efficiency of the slab-sided separation component with a semicircle bottom is higher than the traditional square short component and affected by the air velocity slightly, so this kind of separation component is adapted to be used in the sand/dust test system where air velocity varies in an extensive range. |
