Mixing Performance of an Inline High-Shear Mixer with a Novel Pore-Array Liquid Distributor

A novel pore-array intensified tube-in-tube micro channel (PA) with high throughput was developed to couple with a high-shear mixer (PAHSM) for improving its mixing performance. Effects of structural and operating parameters were intensively investigated with the Villermaux/Dushman system. The results indicated that the mixing performance in PAHSM was significantly impacted by the structural parameters, and it increased with both the rotor speed and flow rate but not with the flow ratio. The micromixing time estimated with the incorporation model could reach 10(-4) s. Compared with other mixing devices, the PA liquid distributor can significantly enhance the mixing performance of HSM with high throughput but low pressure drop. An artificial neural network (ANN) was applied to correlate the micromixing time with the investigated parameters, and the comparison between the model and experimental data indicated that it was an efficient method to fit experimental data in the PAHSM.
