“…The DNV model 38 is an empirical model developed based on several experiments conducted to study the impact of erosive sand particles with different materials, including GRP epoxy which is used in coating wind rotor blades. The DNV model 38 is chosen in the current work because of its accurate results as it was recommended by several researchers such as Huser and Kvernvold 45 to examine sand erosion and wear problems in pipelines; Peng et al 46 who studied erosion roughness of gas pipelines using two-way coupling; in addition to Granberg and Hübert 47 who used an Eulerian-LaGrangian CFD model. In addition some CFD software tools have lately implemented the DNV erosion model, due to its efficiency and accuracy.…”

Sand erosion and dust deposition may induce surface irregularities of the blades of a wind turbine deployed in the Sahara, causing performance deterioration. In the current work a multi-objective optimization algorithm is developed to upgrade the aerodynamic blade profile of wind turbines operating in a Saharan environment. As a case study, the rotor of the Nordtank 300 kW horizontal axis wind turbine operating in Hurghada, Egypt is customized for lower sensitivity to surface roughness. The goal is to achieve a high lift-to-drag ratio while simultaneously maintain high resistance to dust deposition and sand erosion. The optimization algorithm is developed in MATLAB using C-language and coupled via ANSYS-ICEM to ANSYS-FLUENT computational fluid dynamics software for a particle-laden flow simulation until the optimization objectives are iteratively met. The optimization process yields a blade with lower sensitivity to surface roughness issues not only offsetting the 10.58% loss in Annual Energy Production (AEP) using the original profile, but actually boosting the AEP by 10.87% for the optimized blade. It is believed that this research may draw attention to the need for site-specific blade design to avoid environmental surface degradation as a result of dust deposition and sand erosion that may be unavoidable in the Saharan environment of countries in the MENA region.

“…They studied erosion wear of different types of pipes, but the types of pipes studied were not suitable for high-temperature wellhead devices. Peng and Cao 12 studied the effects of different bend diameter ratios and particle diameters on the erosion of the elbow. The study found that the erosion laws before and after the critical diameter of the solid particles were very different.…”

In underground coal gasification, crude gas carrying coal ash and cinder has a serious significant erosion effect on the gas extraction area of a wellhead device. To study the erosion of the wellhead device, based on the gas-solid two-phase flow theory, this study uses the discrete phase model to describe the kinematics and trajectories of discrete solid particles and uses the Reynolds-averaged Navier-Stokes equation to calculate the fluid dynamics of the continuous phase. This study determines the main erosion position and the maximum erosion angle range of the wellhead device through numerical analysis, as well as the influence of the changes in solid particle size, particle mass flow rate, and crude gas flow rate on the erosion rate, and predicts the service lifetime of the small four-way and side valve I. The gas-solid erosion experiment verified the maximum erosion angle of the wellhead device. The experimental results were consistent with the numerical analysis results. This study also proposes an optimization method of surfacing to reduce the erosion of gas-solid two-phase flow on wellhead devices. The results show that the inner walls of the small four-way and side valve I are the most eroded. Factors such as particle size, particle mass flow rate, and crude gas flow rate have a greater impact on the erosion rate of the device, and the particle size has the greatest impact. Surfacing the severely eroded area of the wellhead device can effectively reduce the erosion and wear of the wellhead device caused by the gas-solid two-phase flow. This study provides guidance for the reasonable prediction and effective protection of severe erosion areas of wellhead devices.
