CFD simulation of sand particle erosion in gas-dominant multiphase flow

In the next step, particle tracking and erosion modeling were performed. Specifically, erosion in air-water flow with sand particles of two different sizes (150 and 300 μm) in a 76.2 mm elbow was simulated and compared with experimental data formerly obtained by an ultrasonic technique. Six different erosion equations were employed to discover which equation provides the best predictions. A good agreement was found between CFD results and the experimental data.
