Special Issue Information

Dear Colleagues,

Process intensification is a promising pathway in the development of sustainable and cost-effective chemical process systems. Its realization requires the development, design, and optimization of chemical processes at multiple scales, including the molecular, fluid cluster, equipment, and process scales. This Special Issue aims to provide a comprehensive perspective on this topic to attract widespread attention from scientists and engineering with regard to this concept, in order to build more efficient and eco-friendly chemical processes. The topics we are interested in include, but are not limited to:

  • Process development, design, optimization and integration;
  • Process equipment of reaction, separation, heat transfer, etc.;
  • Synthesis of catalysts and adsorbing material, etc.;
  • Hydrodynamics, mass transfer, heat transfer;
  • Reaction kinetics and mechanism;
  • Molecular design and simulation.

The liquid–liquid two-phase flow and size prediction of slug droplets in flow-focusing microchannels with different downstream orifice sizes were investigated experimentally. Aqueous solution of 50%-glycerol and mineral oil with 4 wt.% surfactant sorbitanlauric acid ester (Span 20) were used as the dispersed and continuous phases, respectively. Three characteristic flow patterns were identified: slug flow, dripping flow, and jetting flow. The slug flow region decreased but the jetting flow region increased with the decrease in the size of the channel orifice. Afterwards, the universal flow pattern maps of the liquid–liquid two-phase in three microchannels were obtained based on dimensionless analysis. Furthermore, two slug droplet formation regions were found: when φ−1Cac < 0.01, the droplet formation was mainly driven by the squeezing force Fp, while when φ−1Cac > 0.01, both the squeezing force Fp and shear force Fτ contributed to droplet formation. Additionally, the prediction correlations of the dimensionless sizes of the slug droplets in both regions were established based on the flow rate ratio of the two-phase, the dimensionless orifice size, and the Capillary number of the continuous phase. The predicted results are in good agreement with the experimental values. Full article
