摘　　要：针对海上某平台下的单弯管和双弯管,采用数值模拟的方法对比分析气体速度、砂粒直径、砂粒质量流量以及弯管曲率半径对两种弯管冲蚀问题的影响规律。结果表明,对两种弯管冲蚀问题影响程度大小顺序依次为气体速度、砂粒质量流量和砂粒直径;弯管曲率半径对冲蚀问题有一定影响,单弯管曲率半径不宜小于1.1 m。在相同条件下,双弯管的最大冲蚀速率要小于单弯管的冲蚀速率,具有更好的耐冲蚀性能,实际使用中应优先选择双弯管结构。The influence of gas velocity,sand diameter,sand mass flow rate and bend curvature radius on the erosion of single elbow and double elbow under an offshore platform is analyzed by numerical simulation.The results show that the order of influence degree on the erosion problems of the two kinds of elbows is velocity,sand mass flow rate and sand diameter in turn.The curvature radius of the elbow has a certain influence on the erosion problems,and the curvature radius of a single elbow should not be less than 1.1 m.Under the same condition,the maximum erosion rate of double elbow is less than that of single elbow,which has better erosion resistance.Double elbow structure should be preferred in practical use.
