“…For gas-solid two-phase flow, flow erosion has been found the main reason causing the pipeline failures [5][6][7][8][9]. In nitrogen drilling, as the compressed nitrogen is continuously expanding in the rising process along the wellbore, the cuttings-carrying flow rate increases quickly and reaches the peak in the inlet of the discharge pipe.…”

In nitrogen drilling, entrained sand particles in the gas flow may cause erosive wear on metal surfaces and have a significant effect on the operational life of discharge pipelines, especially for elbows. In this paper, computational fluid dynamics (CFD) simulations based code FLUENT is carried out to investigate the flow erosion on a sand discharge pipe in conjunction with an erosion model. The motion of the continuum phase is captured based on solving the three-dimensional Reynolds-averaged Navier-Stokes (RANS) equations, while the kinematics and trajectory of the sand particles are evaluated by the discrete phase model (DPM). The flow field has been examined in terms of pressure, velocity, and erosion rate profiles along the flow path in the bend of the simulated discharge pipe. Effects of flow parameters such as inlet velocity, sandy volume fraction, and particle diameter and structure parameters such as pipe diameter and bend curvature are analyzed based on a series of numerical simulations. The results show that small pipe diameter or small bend curvature leads to serious erosion, while slow flow, little sandy volume fraction, and small particle diameter can weaken erosion. The results obtained from the present work provide useful guidance to practical operation and discharge pipe design.

“…Many investigators have also carried out both physical and numerical studies on the erosion of pipe bends (Stack and Abdelrahman, 2011;Zhang et al, 2012;Tan et al, 2012;Li et al, 2010;Suzuki et al, 2008). Zeng et al (2014) have investigated the erosionecorrosion behavior of X65 pipeline elbow by array electrodes technique and CFD simulation.…”

“…Flow erosion, as a hot issue in industrial operations, has attracted many investigators to conduct physical or numerical modeling [2][3][4][5]. Since the early 1990s, with the purpose of saving time and resources and avoiding potential risks, computational fluid dynamics (CFD) as a reliable tool has been widely used for particle erosion prediction in pipe bends, elbows, ducts, tees and related geometries [6][7][8][9][10][11].…”

“…Stack and Abdelrahman [3] have evaluated the effects of particle concentration on the erosion of the inner surfaces of a circular pipe with a 90°bend using a commercial CFD code. Derrick and Michael [6] also used a CFD code to model particle-laden flow and predict erosion in four different 90°square cross-section bends.…”
