Self-propulsion dynamics of small droplets on general surfaces with curvature gradient
Yujuan Chen, Xianmin Xu
We study theoretically the self-propulsion dynamics of a small droplet on general curved surfaces by a variational approach. A new reduced model is derived based on careful computa…
Effective boundary conditions for dynamic contact angle hysteresis on chemically inhomogeneous surfaces
Zhen Zhang, Xianmin XU
Recent experiments (Guan et al. 2016a,b) showed many interesting phenomena on dynamic contact angle hysteresis while there is still a lack of complete theoretical interpretation. I…
Theoretical analysis for dynamic contact angle hysteresis on chemically patterned surfaces
Xianmin Xu, Xiaoping Wang
A dynamic wetting problem is studied for a moving thin fiber inserted in fluid and with a chemically inhomogeneous surface. A reduced model is derived for contact angle hysteresis…
Theoretical analysis for flattening of a rising bubble in a Hele-Shaw cell
Xianmin Xu, Masao Doi, Jiajia Zhou +1
We calculate the shape and the velocity of a bubble rising in an infinitely large and closed Hele-Shaw cell using Park and Homsy's boundary condition which accounts for the change…
Finite element methods for a class of continuum models for immiscible flows with moving contact lines
A. Reusken, X. Xu, L. Zhang
In this paper we present a finite element method (FEM) for two-phase incompressible flows with moving contact lines. We use a sharp interface Navier-Stokes model for the bulk phase…
