摘要:
为了提高天然气输送管道90°弯管的耐磨性能,提出了1种三段弯曲式弯管,通过对弯管弯曲段进行三段式改进来减小弯管中二次流的大小,优化弯管内的流场,改善弯管的冲蚀磨损状况。利用COMSOL仿真软件建立三段式弯管模型,并以弯管弯曲段和出口段二次流平均值之和最小为优化目标,在约束条件下凭借COMSOL中的COBYLA优化算法得到了最优管形;用Fluent对优化后的三段式弯管进行冲蚀数值模拟并与一段式弯管的模拟结果进行对比分析。研究结果表明:与一段式90°弯管相比,优化后的三段式弯管流场更加平稳,其弯曲段的二次流强度大幅降低,弯管壁面的冲蚀磨损程度得到较大的改善。
Abstract:
A threesection bending elbow was proposed to improve the erosion resistance of the 90° elbow in the natural gas transportation pipeline.The threesection improvement was carried out on the bending section of elbow to reduce the secondary flow,optimize the flow field in the elbow,and improve the erosion state of elbow.A model of threesection elbow was established by using the COMSOL simulation software,and taking the minimum sum of average values of secondary flow at the bending section and exit section of the elbow as the objective function,the optimal pipe shape under the constraint conditions was obtained by the COBYLA optimization algorithm in COMSOL.The numerical simulation of erosion was conducted on the optimized threesection elbow by using the Fluent software,and the results were compared with the simulation results of onesection elbow.The results showed that compared with the onesection 90° elbow,the flow field in the optimized threesection elbow was more stable,the intensity of secondary flow at the bending section reduced greatly,and the erosion degree of the inner wall surface of elbow was improved greatly.
