Predicting the material loss around a hole due to sand erosion

Slurry erosion of surface imperfections in pipeline systems

“…Fig. 9 plots GF of the air-based experiments (Wong et al [4,10]) with the water-based experimental results of the current work. GF for the water-based experiments (in the lower Stokes number regime) is in the range of 0.4-0.6, while the air-based experiments report a range that is approximately twice the water-based experiments (0.97-1.11).…”

“…For the weld bead, L is defined as the weld bead length in the streamwise direction. For the hole-in-plate configuration of Wong et al [10], L is defined as the hole diameter. Table 3 details the Stokes number calculation corresponding to GF for various configurations and conditions.…”

“…Material loss can also occur on the joints of pipes [9]. If a pipe has perforated holes to act as coarse filters or pressure drop devices, material erosion on the hole shoulder can also occur [10]. However, there is a lack of data quantifying the erosive effects of slurry flows on protruding weld beads and circular cavities.…”

The Effect of Impingement Velocity and Angle Variation on the Erosion Corrosion Performance of API 5L-X65 Carbon Steel in a Flow Loop

“…The prediction models presented as a function of impingement velocity, angle, particle size/shape and substrate material properties [19][20][21][22]. One of the early erosion prediction models was the one developed by Finnie et al [18].…”

Structural optimization of downhole fracturing tool using turbulent flow CFD simulation

“…Erosion phenomenon which represents a form of material wear and loss has been reported in many areas of oil and gas production (Parsi et al, 2014;Wong et al, 2012). Severe erosion occurred during the fracturing process is undesirable because it will lead to increase of production time and cost (Clem et al, 2006).…”
