Research Abstract

A Model of liquid droplet impingement erosion (LDIE) was developed based on previous model of erosion. The developed model was implemented. If the erosion phenomenon requires a long time, and the time scale is much longer than that of the two-phase flow, the changes in the two-phase flow and the wall shape can be treated by weak coupling. LDIE simulation required droplet impingement velocity and position, and so Euler-Lagrange coupling was selected.
Condensation was considered to obtain position and diameter of droplets. Liquid film and splash are important for LDI erosion process, the modeling becomes complex. The present model was developed considering not only velocity, angle, and material parameter but also liquid film and splash.
The developed procedure was validated by comparing experimental data of bend. Based on the validation, LDIE in a low pressure turbine was simulated, and the present results showed good agreement with experimental data.
