摘要：用脉冲示踪法研究了闭式涡轮转盘塔（ＣＴＲＤＣ）中连续相的轴向扩散系数Ｅｃ与转速ＮＲ、通量Ｖ等操作条件的关系，经回归分析得到Ｅｃ的计算关联式，并且与转盘塔（ＲＤＣ）的研究结果作了比较。实验结果表明：由于闭式涡轮的强烈搅拌作用，ＮＲ大大下降，液滴大小（ｄｐ）分布更均匀。与ＲＤＣ相比。
Investigation on the relationship of axial dispersion coefficient(E\-c) and the operating conditions,such as the rotor speed(N\-R) and the flow rate(U\-d & U\-c),was carried out with the method of pulse input of tracer in CTRDC(rotating disk contactor with closed turbine).The correlation formula for predicting E\-c has been obtained by exponent multiple regression analysis of experimental data.Comparing with that in RDC(rotating disk contactor),smaller E\-c was found in CTRDC through decreasing N\-R and uniformly distributing d\-p by strong agitation of the closed turbine.
