Teaching method for multiphase displacement behavior based on transparent experimental platform

In this paper, an experimental platform was developed for transparent analysis of the multiphase displacement behavior. The 3D printing technology was used to rapidly prepare transparent models with complex discontinuous structures inside. The experimental teaching methods of contact angle measurement, surface tension measurement and multiphase displacement behavior transparent analysis were established, which improved the experimental teaching platforms of engineering fluid mechanics. By conducting multiphase displacement experiments, students can deepen their understanding of textbook theoretical knowledge, broaden their academic horizons, and improve their subjective initiative and innovation ability.
