摘要
采用欧拉-欧拉法,对硫浆在135°弯管内的流动状态进行数值模拟。通过和Toda实验的90°弯头对比进行模型的验证。验证结果表明,模拟值和实验值吻合良好。对相同操作条件下45°和90°弯头的压降进行了比较分析,分析了硫浆体积分数和硫浆速度对弯头压降的影响。同时,研究了硫浆体积分数和硫浆速度对135°弯管内流动状态的影响。对本研究所针对的管道而言,当硫浆体积分数为0.15时,建议输送速度大于1.2m/s。
A numerical simulation study for flow behavior of sulfur slurry in 135° bend pipe has been conducted by Eulerian-Eulerian model. Validation of the models could be obtained from the comparison with a 90° elbow of Toda. The predicted results were in good agreement with experimental data. A general comparison of pressure drop in the 45° and 90° elbow were also discussed in present research at the same operating condition as a reference. The effects of the sulfur slurry volume fraction and sulfur slurry velocity on the pressure drop in elbow as well as on the flow characteristics in 135° bend were studied. In present research, when the sulfur slurry volume fraction was 0. 15, the minimum transport velocity was proposed to be higher than 1. 2 m/s.
