闭式涡轮转盘塔的传质数学模型

Mass Transfer Model for CTRDC

建立了闭式涡轮转盘塔（ Ｃ Ｔ Ｒ Ｄ Ｃ）的传质数学模型——简化的扩散模型，并用数值计算方法求得塔内浓度分布和传质系数 Ｋｏｄａ。计算结果与实验测定值相当吻合，说明模型能较好地反映 Ｃ Ｔ Ｒ Ｄ Ｃ 中的传质状况，可用于 Ｃ Ｔ Ｒ Ｄ Ｃ 塔高的设计计算。

A simplified dispersion model for predicting mass transfer coefficient ( K od a ) and concentration profile in CTRDC has been obtained and solved numerically.The calculated data are quite close to the experiment results.So the present model satisfactorily indicates the mass transfer condition in CTRDC and can be used in operation calculation and scale up design for CTRDC.
