Experimental and Numerical Investigation of the Effect of Viscosity and Particle Size on the Erosion Damage Caused by Solid Particles

Oil and gas produced from wells usually contain impurities such as sand particles transported by fluid flowing through pipelines. The particles impinge on the pipe walls and fittings removing material from the wall and causes erosion damage. The effect of viscosity and particle size on the local thickness loss and total erosion ratio was investigated by conducting a comprehensive experimental study on the erosion of stainless steel 316 specimens caused by sand entrained in a submerged liquid jet. Two types of sand with sizes of 150 µm and 300 µm were used and added to liquids with 1, 14 and 55 cP viscosities. The tests were carried out for three different nozzle angles: 90
