Influence of the shape of quartz sand particles factor on single particle erosion damage

Abstract The paper presents data on the influence of aerodynamic factor of quartz sand particles on a single particle erosion damage as a part of investigation of gas-abrasive wear of field equipment steel elements caused by solid particles impact in conditions of sand production of wells. The studies are mainly focused on calculating geometric characteristics of the crater obtained as a result of a single particle impact, such as maximum penetration depth and equivalent diameter of the crater, affected by the shape of the sand grains. The results have shown the significance of experimental and numerical data, including sphericity, roundness and shape factor of particles determination towards further calculation of particles impact parameters.
