【Abstract】 In this paper the mechanism of the erosion of heated surface of boiler tubes caused by the gas particle flow is studied numerically. The gas particle flow theory and the material erosion theory were combined for the simulation. Beside the effect of the erosion protection method was discussed .The result provides a theoretical basis for the practical engineering.更多还原
