    Abstract
  • In view of the deposition of micro particles on the surface of turbine blades，the EI-Batsh deposition model was used to simulate the deposition of micro particles on the surface of turbine blades to explore the effect of pressure surface cooling jets on particle deposition characteristics.Results showed that，particles were mainly deposited on the leading edge and pressure surface of the blade，and the deposition rate increased with the particle diameter.However，when the particle diameter increased to 17 μm，the increase of deposition rate began to decrease.When there was a cooling jet，the collision rate of small particles can be affected by off and entrainment，thereby affecting the deposition rate.But there was basically no impact on the collision rate of large particles.The jet can also reduce the particle adhesion rate by cooling the wall surface，and affect the deposition rate in this way.The large-size particles were affected more obviously.After changing the blowing ratio，the particle deposition rate decreased first and then increased as the blowing ratio increased.
