摘要/Abstract

摘要：

针对一种新型锥形式旋叶汽水分离器开展全尺寸的蒸汽-水热态试验和数值模拟研究.试验结果表明:汽水分离效率随着蒸汽表观速度的增大先减小后增大,但在低蒸汽表观速度区变化不敏感;分离器压降随着蒸汽表观速度的增大而显著增大.基于商业计算流体软件STAR-CCM+,利用Euler-Euler两流体模型方法开展旋叶分离器数值模拟,研究液滴粒径对汽水分离效率和压降的影响.计算结果表明:大粒径的液滴有利于液相的分离,但液滴粒径对压降的影响较小.根据试验研究建立了与试验结果吻合较好的数值计算模型,系统地分析了分离器压力场、速度场和液相体积分数的分布规律.

Abstract:

A full-scale novel conical swirl-vane steam separator with a conical barrel is studied by test and numerical methods using steam and water as working fluids. The test results indicate that the separation efficiency of the separator decreases first and then increases with the increase of steam superficial velocity. But this phenomenon is not obvious at low steam superficial velocities. The pressure drop of the separator increases significantly with the increase of steam superficial velocity. Based on the commercial software STAR-CCM+ and Euler-Euler two-fluid model, a numerical simulation is conducted to study the effect of droplet size on the separation efficiency and pressure drop of the swirl-vane separator. The numerical results imply that large droplets promote the liquid separation. However, the pressure drop is insensitive to the droplet size. According to the test results, a numerical model that is in good agreement with the test is established, and the distribution of presssure, velocity, and water volume fraction are analyzed in detail.

Key words: swirl-vane steam separator, thermal test, numerical simulation, separation performance, flow field
