First, the classic configuration of a particle separator based on the literature is simulated using two boundary conditions. The results show that the boundary conditions for the total pressure inlet and mass flow outlet are much more closely aligned with the experimental environment. By modifying the material at the front of the shroud, the separation efficiencies of coarse Arizona road dust (AC-Coarse) and MIL-E-5007C (C-Spec) can be improved to 93.3% and 97.6%, respectively. Configuration modifications of the particle separator with dual protection can increase the separation efficiencies of AC-Coarse and C-Spec to 91.7% and 97.7%.<\/jats:p>","DOI":"10.3390\/e25010147","type":"journal-article","created":{"date-parts":[[2023,1,12]],"date-time":"2023-01-12T06:32:26Z","timestamp":1673505146000},"page":"147","source":"Crossref","is-referenced-by-count":2,"title":["Sand Discharge Simulation and Flow Path Optimization of a Particle Separator"],"prefix":"10.3390","volume":"25","author":[{"given":"Zhou","family":"Du","sequence":"first","affiliation":[{"name":"School of Mechanics and Engineering, Liaoning Technical University, Fuxin 123000, China"},{"name":"Institute for Aero Engine, Tsinghua University, Beijing 100084, China"}]},{"given":"Yulin","family":"Ma","sequence":"additional","affiliation":[{"name":"School of Mechanics and Engineering, Liaoning Technical University, Fuxin 123000, China"}]},{"given":"Quanyong","family":"Xu","sequence":"additional","affiliation":[{"name":"Institute for Aero Engine, Tsinghua University, Beijing 100084, China"}]},{"given":"Feng","family":"Wu","sequence":"additional","affiliation":[{"name":"AECC Sichuan Gas Turbine Establishment, Mianyang 621000, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"135","DOI":"10.2514\/3.45097","article-title":"Analysis of a Split-Flow Inertial Particle Separator by Finite Elements","volume":"22","author":"Breitman","year":"1985","journal-title":"J.
