摘要

从基本的一维两液体模型出发

全面地考虑了气升式反应器中气体膨胀、气液两相间相互作用和滑移等

建立了反应器的一维模型。通过数值方法求解整个反应器的流体力学方程组。解的结果包括气含率、气体和液体速度等

作者将模型计算结果与大量的实验数据进行了比较

两者相符较好。

Abstract

A one -dimensional two -fluid model for air -lift reactors (ALR) was developed. The model takes into account the variation of gas density due to expansion in the reactor

veloctity slip and interaction between gas and liquid. Numerical solution of the model equations leads to the main characteristics of fluid flow such as liquid velocity and gas holdup. A method for estimating downcomer gas holdup was proposed. Experimental data on both external and internal ALRs were compared with the theoretical prediction and the agreement was found rather satisfactory.
