摘要

本文研究非牛顿幂律流体传质过程

实验采用淋降塔装置

测定高聚物溶液的传质速率.实验结果表明传质速率随温度和溶液流量增加而增大

还随压力和溶液稠度系数下降而增加.并应用相似论原理分析非牛顿幂律流体传质过程

得到柯尔本因子与雷诺数关系式j_m=BRe~B_1

由实验数据经线性回归得到B=2.2708×10~(-5)

B_1=-0.7013相关系数0.99.

Abstract

A dripping plate column fitted with perforated trays was used in studying the mass transfer for non-Newtonian liquids. The rate of vaporization of aqueous polymer solutions rheological behavior with power-law was measured in the column. It was found that temperature

pressure

mass flow rate and the non-Newtonian behavior of the solution are significant factors influencing mass transfer rate

which increases with increasing temperature and mass flow rate

and with decreasing pressure and fluid consistency. Based on these experimental data

a correlation for the Colburn factor

was developed: jm= 2.2708 × 10-5Re-0.7013 It can be used to design flash columns for monomer discharge from polymer solutions.
