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…

Fluctuation-driven dynamics of liquid nano-threads with external hydrodynamic perturbations
Zhao Zhang, Chengxi Zhao, Ting Si
Instability and rupture dynamics of a liquid nano-thread, subjected to external hydrodynamic perturbations, are captured by a stochastic lubrication equation (SLE) incorporating th…
