Abstract

Abstract:

Microdispersion is an important part of micro chemical engineering technology. The complexity of equipment and processes imposes many limitations on its related research. Under the guidance of traditional thinking, the basic research on microdispersion follows the approach of “design-experiment-modeling”, resulting in slow progress. In recent years, artificial intelligence (AI) methods have received increasing attention in chemical engineering due to their powerful recognition and regression capabilities. AI-assisted basic research on microdispersion is conducive to forming a new paradigm for understanding micro chemical engineering processes, promoting the development of micro chemical engineering technology. This article introduces the general idea of AI methods and their applicability to microdispersion investigation, reviews the developments of AI technology in microscopic image recognition, droplet and bubble dispersion size prediction, and microdispersion process control and optimization, and offers insights into the prospective directions of micro chemical engineering based on AI technology.

Key words: microfluidics, dispersion, model, algorithm, artificial intelligence
