The product distribution of two sets of multiple reactions were observed to depend upon the impeller speed and the feed location in a semibatch stirred-tank reactor as well as upon the viscosity. A new method to predict the product distribution of one reaction set based upon measurements for the other and a micromixing model is developed, subject to approximations which are explained. Examples of...
When the impeller Reynolds number is sufficiently high, so that the turbulence in a stirred tank is fully developed, the macroscopic flow characteristics, e.g. velocity distribution, power consumption and bulk blending time, are independent of viscosity. However, the fine-scale characteristics, near the Kolmogorov microscale, are influenced by viscosity and an effect on micromixing must be expected...
