In order to predict and evaluate erosion of products with particle-gas flow, an Erosion simulator is developed.The simulator is constructed from (1)erosion prediction model, (2)erosion basic test, (3)particle movement analysis by CFD. In this research, the equations of Finnie and Bitter are adapted as the erosion prediction model. The experimental fixed values in the model are obtainable by a centrifugal erosion tester. In order to ascertain this method's validity, simulation was compared with erosion depth of 12x4 tube array erosion test. As a result, the prediction of erosion depth generally agree with those obtained by the experiment, and it is seen to be able to estimate the erosion characteristic of tube bundle.
