Influence of van der Waals forces on the instability of a liquid film in a tube
Yixiao Mao, Chengxi Zhao, Yixin Zhang +2
The instability of a liquid film in a nanotube is significantly influenced by van der Waals forces. A theoretical framework based on the axisymmetric Stokes equations is developed…

Spatial instability analysis and mode transition of a viscoelastic jet in a co-flowing gas stream
Jiawei Li, Ming Wang, Kai Mu +2
Spatial linear instability analysis is employed to investigate the instability of a viscoelastic liquid jet in a co-flowing gas stream. The theoretical model incorporates a non-uni…

Capillary-driven migration of droplets on conical fibers
Yixiao Mao, Chengxi Zhao, Kai Mu +2
A droplet placed on a hydrophilic conical fiber tends to move toward the end of larger radii due to capillary action. Experimental investigations are performed to explore the dynam…
