Erosion experiments were conducted with gas-sand and gas-liquid-sand flow conditions varying air and water velocities in a laboratory scale Gas-Liquid Cylindrical Cyclone Separator (GLCC). The location of highest erosion measured for gas-liquid-sand conditions was slightly above the case for the gas-sand condition, but the magnitude of erosion for the latter case was much higher than the former. Therefore, it appears that the presence of a small amount of liquid in this geometry reduces the peak value of measured erosion. Computational Fluid Dynamics (CFD) simulations are also conducted for gas-sand flows to aid in the understanding of the particle flow characteristics and maximum wall thickness loss inside the GLCC. The results from the simulation are compared to experimental data for several conditions. A simplified erosion prediction model has been also developed to predict the erosion occurring at the inlet nozzle region of the GLCC. The model predictions agree much better with data than those previously obtained for the GLCC geometry that was based on an elbow but similar methodology was applied.
