This paper attempts a qualitative and quantitative comparison of the calculation results of multiphase flow gas - solid particles in a flow system with built-in bend. The movement of the gas phase and particle trajectories are described by Euler and Lagrange models respectively. Simulation tests were performed for several different inlet conditions, in order to determine their impact on results. The study allowed us to identify the model of Euler-Lagrange as useful for this type of flows, and the formulation of a number of important conclusions. The paper presents the possibility of applied mathematical models to predict the erosive wear of flow system with built-in elbow. The emphasis of the work was put on qualitative comparison the effect of inlet conditions on the change of the gas velocity field and the concentration of particulate matter. These elements made it possible to locate areas of increased wear as well as the degree of wear.
