EVALUATION OF NUMERICAL MODELS FOR PREDICTION OF AREAS SUBJECTED TO EROSION WEAR

Abstract

The paper compares different erosion models. The calculations were carried out in a selected flow system, and results were compared with experimental results of this system. The motion of gas phase was described by Reynolds equations and the particle trajectory was calculated by using Lagrange’s method. The simplifications and the different ranges of models’ application do not allows us to state which model assures correct results in complicated conditions of flow. For that reason was performed research for a part of the dust system in BP-1150 boiler.
