The present paper predicts numerically the impaction and the erosion of the tube row by coal ash particles. The two-dimensional turbulent gas flow field is obtained by solving the governing equations, using the so-called SIMPLE scheme. The present calculation of particle trajectories in particle laden flow around the tube row takes into account the effect of the turbulence of the fluid flow with a stochastic particle dispersion model, as described recently by the authors. The impact and rebound model and the erosion model obtained by Tabakoff el al. are used in the paper to predict the particle rebound and the erosion damage of tube row. The present paper discusses the effect of the velocity and the particle size on the frequency of impact and on the erosion damage. The maximum erosion damage locations of the tube row are predicted. Some predicted results are compared with the experimental data. @KEYWORDS: Erosion prediction, Tube row, Coal ash impaction. |
