In order to explore the dynamic characteristics of particle deposition in the turbine guide vane of aero-engine and the influence of deposition morphology on heat transfer characteristics, numerical simulation was carried out for the combined cooling structure of single-layer film hole wall on the pressure surface and impingement-film hole overflow on the suction surface. The total pressure of the mainstream inlet of the cascade was 3.09 MPa, the static pressure of the outlet was 1.52 MPa, and the total temperature of the mainstream inlet was
