Computational Analysis of Water-Submerged Jet Erosion

Erosion causes substantial damage in many industrial equipment such as pump components, valves, elbows, and plugged tees. In most cases, erosion is coupled with corrosion, resulting major financial loss (nearly 3.4% of the global gross domestic product) evidenced oil gas industries. occurs a submerged water medium. this paper, characteristics stainless steel 316 were investigated computationally water-submerged jet impingement setup. The profiles patterns obtained for various parameters over ranges inlet velocities (3 to 16 m/s), nozzle diameters (5 10 mm), nozzle–target distances 20 shapes (circular, elliptical, square, rectangular), angles (60° 90°), particle sizes (50 300 µm). range Reynolds number studied based on 21,000–120,000. Eulerian–Lagrangian approach was used flow field prediction tracking considering one-way coupling particle–fluid interaction. Finnie model implemented ANSYS-Fluent 19.2 prediction. computational validated against experimental data distributions depth well locations maximum minimum points are matched. As expected, results indicate an increase material thickness increasing velocity. Increasing diameter caused reduction eroded due decreasing impact density. At fixed fluid velocity, increases separation distance between outlet target increases, aspect ratio shape decreases, angle increases. showed that region size/stand-off height size decreases. addition, creates skewed patterns.
