Abstract：

Addressing the abstract and challenging nature of dimensionless quantities such as Weber number(We) and Reynolds number(Re) in fluid mechanics, this paper uses droplet wetting coal dust as an engineering carrier to construct a five-dimensional teaching system that integrates “thought and education, virtual and real reinforcement, beauty and force, innovation and creativity, and practical exploration.” The physical significance of We-Re is analyzed, virtual-real collaborative experiments are designed, scale-law models are established, parameter correlation analysis is conducted, and scientific poetry and paintings are innovatively introduced to aid understanding, emphasizing the integration of thought and education. Teaching practice shows that this five-dimensional teaching system can promote the innovation and development of educational and teaching theories, guide students to immerse themselves in theoretical innovation, practical exploration, and poetic and pictorial sentiments, stimulate students' learning interest, enhance their learning effectiveness, and cultivate their innovative abilities.

Key Words： dimensionless quantity;liquid droplet wetting;five-dimensional teaching system;scientific poetry and painting
