摘要

介绍一种新型穿流塔板——正交波纹板。以欧拉-欧拉两相流模型为基础

建立了正交波纹板上气液两相流场的三维数学模型。CFD模型中主要考虑了气液两相间的曳力作用

相间动量传递源相采用Krishna计算方法。以清液层高度为指标

对CFD模型的可靠性进行了验证。在不同气液负荷下

对正交波纹板的压降、板上液相速度分布及塔内气液分布状况等流体力学性能进行了研究

并与淋降筛板进行对比

结果表明正交波纹板具有更高的操作弹性和更好的操作稳定性。

Abstract

The orthogonal wave type (OWT) tray

a new type of dual flow tray

was developed. A 3D transient computational fluid dynamics model in the Eulerian-Eulerian framework is developed to predict the hydrodynamics of OWT tray. Drag force is mainly considered as the interphase momentum exchange term and calculated using the Krishna correlation. Simulated clear liquid height is in good agreement with the experimental value. The hydrodynamics including pressure drop

liquid velocity and gas-liquid distribution under various gas and liquid rates are investigated. Comparison with sieve tray without downcomer shows that OWT tray has an improved turn down ratio and stability.
