“…6b, 7b and 8b, the unstable nature of the cyclic fluctuations observed here can be attributed to the complex and undefined nature of the liquid and gas phases. Case 3 is the validation case for this study and results generated have shown good agreement with the experimental data from Parsi et al [14]. The huge wave observed by Parsi et al [14] can also be seen in Fig.…”

“…3. These conditions were observed on the flow regime map employed in Parsi et al [14], the test cases cut across 6 different flow patterns that can be observed in vertical pipes. The superficial liquid velocity (Vsl) was kept constant at 0.3m/s while the superficial gas velocity (Vsg) was varied.…”

“…Results showed good agreement with available data, however, effects of particle interaction was assumed negligible. Parsi et al [14] presented results from CFD simulation of gas dominant multiphase flow in elbows from their study of churn flow. They employed three different superficial gas velocities of 10.1, 18.3 and 27.1 m/s while that of the liquid remained constant at 0.3 m/s.…”

Erosion caused by sand particles is a serious problem facing the oil and gas industry. Predicting pipe erosion due to sand transport is a complex process in multiphase flows due to the complex nature of the flow. Existing erosion studies are however focused on single phase flow conditions which are conservative and could lead to under-/ over-engineering because actual fluid flow in pipelines is multiphase. There is therefore a need for in-depth analysis of the complex interaction between the multiphase fluid and transported sand particles. This study employs CFD modelling techniques to investigate the complex interactions between the multiphase fluid and transported sand particles in pipes, and the subsequent effect on pipe erosion rate and location under varying operating conditions. In view of this, the Eulerian Multifluid-VOF Model coupled with Interfacial Area Transport Equations have been employed to simulate airwater two phase flow and the result shows good agreement with experimental data. This fluid flow results have been employed in investigating sand erosion in multiphase flow through pipes. The Eulerian Multifluid-VOF model has been coupled with the Lagrangian framework for particle tracking and an appropriate erosion correlation has been employed to predict the pipe erosion rate. The pipe was observed to erode more 45 degrees into the elbow and maximum erosion rate is 4.028e-6 kg/m 2 s. These results are in acceptable range when compared to available data. Erosion rate was also observed to be transient.

In gas and oil industry, erosion damage to pipelines' bends and elbows due to the presence of sand particles has been a challenging issue. In this study, a computational model approach was used to evaluate the erosion rates at di erent vertical return bends: sharp bend, standard elbow, 180 pipe bend, and long elbow. The air ow in the pipe was simulated using the SIMPLE method and the k ! SST turbulence model. An Eulerian-Lagrangian approach was used to predict particle trajectories and related erosion rates. Di erent particle sizes and mass ow rates were considered, and Oka model was used in these simulations to evaluate the erosion rate. Under the same condition, the simulation results indicated that the sharp return bends experienced the highest erosion rates, and the 180 bends experienced the lowest erosion among the studied con gurations. It was also found that the erosion rate was linearly proportional to the mass ow rate of particles for all cases studied. contributions are in the elds of computational uid dynamics, multiphase ows, particle transport, heat transfer, thermal systems, and energy management.

“…In recent years, new methods such as the discrete element method in solid mechanics, and CFD in fluid mechanics, have been applied increasingly to models of major geometric erosion [19,20]. Parsi et al performed a numerical erosion analysis with ANSYS Fluent to determine the erosion of solid particles in the pipeline [21]. However, the authors did not discuss and study the erosion protection at the elbow.…”

In this study, titanium alloy (Ti-4Al-1.5Mn), magnesium alloy (Mg-Li9-A3-Zn3), or aluminum alloy (Al7075-T6) were used to construct the shell model of helicopter rotor blade to study the solid particle erosion of helicopter rotor blades. The erosion resistance of the three materials at different angles of attack (6°, 3°, or 0°) and particle collision speeds (70, 150, or 220 m/s) was examined using the finite volume method, the discrete phase method, and erosion models. In addition, the leading edge of the helicopter blades was coated with two types of bionic anti-erosion coating layers (V- and VC-type), in an attempt to improve erosion resistance at the angles of attack and particle collision speeds given above. The results showed that Ti-4Al-1.5Mn had the best erosion resistance at high speed, followed by Al7075-T6 and Mg-Li9-A3-Zn3. The angle of attack appeared to affect only the surface area of the blade erosion, while the erosion rate was not affected. Finally, the results of this article showed that the V-type bionic coating had better erosion resistance than the VC-type coating at the same impact speeds. The angle of attack did not have a significant effect on the erosion rate of the bionic coating.
