摘要
The micro-mixing time in a continuous system is studied with the incorporation model,in which the direct and indirect solutions are compared and the assumptions and parameters are modified to suit for the continuous system.Results showed that the direct solution is more close to the real mixing state,which is strongly affected by the change of the concentrations in the surroundings caused by the ratio of the continuous flows.While,the real concentrations in the aggregate have significant effect on both the solutions,even more than ten times,especially cH+ in the aggregate.By fitting,the relationships of Xs and tm resulted from both solutions are similar,lgXs is linear to lgtm when tm<0.01 s,and is quadratic when tm is larger.
The micro-mixing time in a continuous system is studied with the incorporation model, in which the direct and indirect solutions are compared and the assumptions and parameters are modified to suit for the continuous system. Results showed that the direct solution is more close to the real mixing state, which is strongly affected by the change of the concentrations in the surroundings caused by the ratio of the continuous flows. While, the real concentrations in the aggregate have significant effect on both the solutions, even more than ten times, especially cH+ in the aggregate. By fitting, the relationships of Xs and tm resulted from both solutions are similar, 1gXs is linear to lgtm when tm〈0.01s, and is quadratic when tm is larger.
