Abstract:To efficiently improve the separation efficiency of larger particles without altering the geometry, the two-phase flowfield within a typical vaneless inertial particle separator was calculated and then carefully studied by using numerical method. Three basic patterns of inertial-dominated particle motion were firstly obtained through an in-depth study on the particle trajectories. Then, taking advantage of the differences of three typical materials in particle rebound characteristics, namely, 2024 aluminum alloy, 7020 rubber and 45 steel alloy, a novel inertial particle separator was designed on the basis of the profound understanding of particle motion. The results show that the separation efficiency of the AC dust and C-spec. sand can be thus raised by 6.0% and 13.7%, respectively. © 2018, Editorial Department of Journal of Aerospace Power.
