A numerical simulation is conducted to obtain more accurate distribution of particle deposition on turbine blade with Jim Bridger Power Station (JBPS). C++ is used to code suitable User Defined Function (UDF), which reconstructs grids to accomdate complex boundary deformation in every time step. In such a way that deposition can change geometry features and heat transfer characteristics, and the whole deposition process on blade can be analyzed and the exact deposition distrbution can be obtained. A fair comparison of numerical results with existing experimental results shows the rationality and accuracy of grid reconstruction code. On the basis of deposition distribution and geometry deformation of turbine blade, the erosion area on the blade is predicted. Thereafter, the effect of mainstream temperature and particle diameter is analyzed. The research results show that the main deposition occurs on the central area of blade pressure side, whereas there is obvious deformation in leading edge and central area. The obvious deformation reveals that roughness is increased and erosion is more severe on leading edge. The diameter of particle has important influence on particle deposition and deposition rate, whereas temperature of mainstream only has influence on deposition rate.
