In order to reveal the particle deposition distribution inside the cascade, reduce the particle deposition, a numerical investigation is performed on the movement and deposition of dilute particles inside a two-dimensional turbine cascade, focusing on the effects of particle diameter and flow incidence angle on movement and particle deposition characteristics. Based on the EI-Batsh deposition model including particle sticking/rebounding and particle detachment, the investigation links user definition functions with Fluent to predict particle deposition. A comparison of the numerical results with existing experimental data shows that the present numerical model is valid. The research results show that particles with larger particle diameters do not follow air flow easily, thus exhibiting a higher collision rate and lower sticking rate. Particles with smaller particle diameters have the opposite tendency. Particle deposition mainly occurs on the central area of the blade pressure surface. The flow incidence angle has important influence on particle deposition distribution.
