Analyzing Mixing Time Measuring Method and Simulation of Mixing Process

The mixing time measured by iodine solution fading is analyzed basing on the turbulence theory and micromixing theory. The mathematic model has been developed for macromixing and micromixing in the fading process, and the model parameters for three kinds of impellers are given. It is pointed out that the ratio of macromixing time to total mixing time increases with the increase in power consumption by calculation.
