摘要

本研究结合实验和数值模拟数据,建立了碳化硅陶瓷和 YW3 的侵蚀模型。该模型可用于天然气设备和运输系统的侵蚀预测,同时也为侵蚀模型的建立提供了思路。以石英砂、棕刚玉和玻璃珠为磨料建立了侵蚀模型,然后通过数值模拟证实了侵蚀模型的准确性。结果表明,当磨料为石英砂、棕刚玉或玻璃珠时,碳化硅和 YW3 发生最大侵蚀的侵蚀角度与磨料类型有关。当磨料为石英砂、棕刚玉和玻璃珠时,碳化硅的速度指数 n 分别为 3.24、3.66 和 3.32,模型常数 k 分别为 4.1959 × 10-11、3.6436 × 10-11 和 4.1838 × 10-11。YW3 的速度指数 n 分别为 2.29、2.41 和 1.87,模型常数 k 分别为 2.6176 × 10-7、3.0017 × 10-7 和 3.1040 × 10-7。将试验结果与数值模拟结果进行比较,碳化硅的最大误差分别为 6.59%、7.71% 和 9.25%,YW3 的最大误差分别为 8.78%、9.51% 和 5.97%。最后,通过大量实验和数值模拟,建立了碳化硅陶瓷和 YW3 的侵蚀模型。当目标材料和磨料材料相同时,可直接用于天然气设备的侵蚀预测和结构优化。同时,本文为气固两相侵蚀模型的建立提供了一种新的思路,当磨料和靶材发生变化时,可根据本文的思路建立新的侵蚀模型。

Erosion model of silicon carbide ceramics and YW3
In this study, an erosion model of silicon carbide ceramics and YW3 was established by combining experimental and numerical simulation data. This model can be applied for the prediction of erosion in natural gas equipment and transportation systems and also provides ideas for the establishment of erosion models. The erosion model was established by using quartz sand, brown corundum, and glass beads as abrasive materials, and then the accuracy of the erosion model was confirmed by numerical simulations. The results showed that when the abrasive was quartz sand, brown corundum, or glass beads, the erosion angle at which the maximum erosion of silicon carbide and YW3 occurred was related to the type of abrasive. When the abrasive was quartz sand, brown corundum, and glass beads, the velocity index n of silicon carbide was 3.24, 3.66, and 3.32, respectively, and the model constant k was 4.1959 × 10−11, 3.6436 × 10−11, and 4.1838 × 10−11, respectively. The velocity index n of YW3 was 2.29, 2.41, and 1.87, respectively, and the model constant k was 2.6176 × 10−7, 3.0017 × 10−7, and 3.1040 × 10−7, respectively. When the test results were compared with the numerical simulation results, the maximum error for silicon carbide was 6.59%, 7.71%, and 9.25%, respectively, and the maximum error for YW3 was 8.78%, 9.51%, and 5.97%, respectively. Finally, the erosion model of silicon carbide ceramics and YW3 was established via a large number of experiments and numerical simulations. When the target material and abrasive material are the same, it can be directly used for erosion prediction and structure optimization of natural gas equipment. Meanwhile, this paper provides a new idea for the establishment of gas–solid two-phase erosion model, and when the abrasive material and target material change, a new erosion model can be established according to the idea of this paper.
