Abstract: The erosion of internals is a major problem in fluidized beds. This review collects, discusses, and compares key experimental and numerical results on erosion of internals immersed in fluidized bed with Geldart B (sometimes near D) particles, comparing the different models and experimental data available in the literature. The erosion models were classified into two categories, depending on the nature of the considered variables. Microscopic erosion models that use particle-scale variables, such as the velocity of the impinging particle or local void fraction; and macroscopic erosion models, which rely on macroscopic features of the fluidized bed, such as air flow rate, bubble size and distribution or height above the distributor.
