英文摘要	In order to study the influence of gas-solid two phase on airfoil laminar separation and transition, the transition performance simulations of flat-plate and S809 airfoil were firstly performed with Transition SST model, and the simulation results were compared with the experimental results, verified the advantages of the Transition SST to simulate boundary layer transition. Then the simulation on the special airfoil of DU93-W-212 was performed under the conditions of clear air and gas-solid two phase flow with different size particles. According to comparing and analyzing the intermittency factor and the friction cofficient, it found when the particles diameter is smaller than 150 μm, the airfoil laminar separation and transition are advanced due to the addition of particles, and the smaller the particle diameter, the more position in advance. When the particles diameter is bigger than or equal to150 μm, the positions of airfoil laminar separation and transition are almost identical to that of clear air. © 2019, Editorial Board of Acta Energiae Solaris Sinica.
