“…In 1996, McLaury proposed an erosion model suitable for water-carrying sand, , which is mainly used to simulate the erosion caused by solid–liquid flow. The mathematical expression is as follows: where F is an empirical constant; Bh is the Brinell hardness value of the wall target, N/mm 2 ; and k is 0.59 when the target material is steel.…”

“…Combining the Euler−Euler method with the Oka erosion model, satisfactory results can be obtained in the flow of compressible gas containing particles. Farokhipour et al 9 used the CFD-DEM method to analyze the practicability and feasibility of a plugging tee to replace conventional elbows. Peng et al 10 analyzed the effects of different flow rates, sand input, particle size, and shape factors on the erosion of shale gas rectifiers and verified them with the erosion test results of the University of Tulsa.…”

In a shale gas gathering and transportation station, the sand particles that are not separated by the upstream desander will cause erosion damage to the vertical separator. In response to this problem, based on the field data of a production well in the Changning area, the corresponding mathematical model and vertical separator geometric model were established. On the basis of the software FLUENT, the effects of different gas velocity, particle size, and sand mass flow on the erosion of the separator and the motion of particles were simulated. The corresponding results show that the erosion scar of the inlet baffle presents a ring shape, and the maximum erosion position on the wall changes with the increase of gas velocity. The erosion rate of the inlet baffle is proportional to the sand flow rate and geometrically related to the gas velocity; the maximum erosion rate of the vertical separator is 520 μm/a under the conditions of 6 kg/d sand input; the separation efficiency decreases with the increase of particle size and speed.

“…Particles are more uniformly distributed in a lowspeed flow, rebound effect attenuates the direct collisions against the same spot. Farokhipour et al (2019) used the CFD-DEM method to study the effects of mass loading and one-, two-and four-way coupling regimes on the model prediction on erosion rate. The simulation results indicated that, as the particle mass loading increases, the effectiveness of plugged tee compared to the standard elbow increases, and influence of particles interaction with flow and particle collision cannot be neglected.…”

In this work, computational fluid dynamics (CFD) is used to study elbow erosion due to a gas–solid two-phase flow. In particular, the direct simulation Monte Carlo (DSMC) method is used to study the impact of inter-particle collision on the erosion behavior. The two-way coupled Euler–Lagrange method is used to solve the gas–solid flow, and the DSMC method is used to consider the collision behavior between particles. The effects of key factors, such as the particle concentration distribution and inter-particle collision, on the erosion ratio are evaluated and discussed. The effectiveness of the method is verified from experimental data. The results show that the inter-particle collision significantly influences the particle movement path and erosion ratio. When the inter-particle collision is considered, the maximum erosion position is offset. The erosion model proposed by Oka et al., who used the DSMC method, agrees best with the experimental data, and the average percentage error decreases from 39.2 to 27.4%.

“…The results showed that the simulation results well predict the maximum erosion position, but there was numerical deviation. Farokhipour et al 12 studied the wear characteristics of elbow and plug tee by CFD-DEM method. Considering the rebound mechanism model, particle rotation and particle collision, the erosion values match the experimental data.…”

As the transportation pipeline of adsorbent in S Zorb regeneration system, due to large mass flow rate of particle and gas, it is often seriously worn, and even perforated, resulting in the leakage of adsorbent. It brings great inconvenience to the transportation of regenerated adsorbent and threats its long-term operation. Therefore, it is essential to study the erosion characteristic of Y-shaped adsorbent transportation pipe. It was studied by computational fluid dynamics (CFD) numerical simulation and the calculation results were validated by actual erosion profile. The results show that the high velocity of nitrogen and the high weight-fraction adsorbent particles accumulation is the key factor leading to severe erosion. It is also found that the small angle cutting is the erosion form. The effects of the intersection angle between the transportation pipe and feed pipe and the gas inlet velocity on the particle motion and erosion characteristics turn out to be significant. The research on the wear characteristics of adsorbent transportation pipeline can provide a certain reference for erosion prevention and optimization.
