🌀 Areas of Expertise

Dr. Z’hen’yan Xia specializes in Fluid Mechanics, Molecular Dynamics, Physical Analytical Chemistry, and Advanced Materials. His work combines both theoretical research and engineering applications, pushing the boundaries of fluid flow control and molecular interactions at macro and nanoscale levels.

🔬 Research Interests

Dr. Xia’s research focuses on two primary areas. The first is turbulent flow control and fluid instability, where he conducts theoretical research and engineering applications aimed at improving fluid flow efficiency in various engineering systems. His second area of focus is the molecular dynamics of fluid-micronano structures, where he explores the fundamental interactions between fluids and micronano surfaces, optimizing fluid behavior at microscopic levels.

🚀 Research Innovations

Reducing the contact time between liquid droplets and solid surfaces is a crucial challenge in many engineering applications. While extensive studies have been conducted on droplet impact mechanisms, there is still a lack of systematic research on nanodroplet behavior on superhydrophobic surfaces with square ridges. Dr. Xia’s research addresses this gap by investigating nanodroplet interactions on both superhydrophobic planes and structured surfaces. His findings reveal that when nanodroplets impact a superhydrophobic plane, the droplet contraction time determines the total contact time. However, when nanodroplets impact superhydrophobic surfaces with square ridges, the critical factor influencing contact time is the detachment time as the droplet lifts off. Additionally, his research highlights that nanodroplets exhibit stronger adhesion to solid surfaces compared to larger droplets and are also more resistant to deformation and splitting, a characteristic not commonly observed in macroscopic droplets. Dr. Xia introduces the critical rebound Weber number (We) to evaluate how square ridges enhance droplet rebound performance. His study demonstrates that a moderate increase in ridge height helps in reducing contact time, while narrower ridges are more effective in minimizing contact duration and facilitating droplet splitting.
