摘要: 

In this work, we derive a thermodynamically consistent continuum model for the dynamics of two immiscible fluids on a thin and inextensible elastic sheet. With the sheet being modelled by a deformable curve with the Wilmore energy and local inextensibility constraint, we derive a two-phase hydrodynamics model with the interfacial and boundary conditions consistent with the second law of thermodynamics. Numerical solutions for the coupled fluid-sheet dynamics are obtained using the finite element method. Numerical study of the droplet relaxation dynamics on an elastic sheet and the transport of a droplet driven by bendotaxis are presented. Furthermore, we also study the bubble dynamics as well as the sheet deformation if the sheet is semi-permeable.
