Abstract Fluid deformable surfaces show a solid–fluid duality which establishes a tight interplay between tangential flow and surface deformation. We derive the governing equations as a thin film limit and provide a general numerical approach for their solution. The simulation results demonstrate the rich dynamics resulting from this interplay, where, in the presence of curvature, any shape change is accompanied by a tangential flow and, vice versa, the surface deforms due to tangential flow… 

Active flows on curved surfaces

We consider a numerical approach for a covariant generalised Navier-Stokes equation on general surfaces and study the influence of varying Gaussian curvature on anomalous vortex-network active

Finite element discretization methods for velocity-pressure and stream function formulations of surface Stokes equations

In this paper we study parametric TraceFEM and parametric SurfaceFEM (SFEM) discretizations of a surface Stokes problem. These methods are applied both to the Stokes problem in velocity-pressure

Active Nematodynamics on Curved Surfaces – The Influence of Geometric Forces on Motion Patterns of Topological Defects

We derive and numerically solve a surface active nematodynamics model. We validate the numerical approach on a sphere and analyse the influence of hydrodynamics on the oscillatory motion of

Interacting active surfaces: a model for three-dimensional cell aggregates

A modelling and simulation framework for cell aggregation in three dimensions based on interacting active surfaces that opens the door to the systematic exploration of the cell to tissue-scale mechanics of cell aggregates, which plays a key role in the morphogenesis of embryos and organoids.

A finite element approach to incompressible two-phase flow on manifolds

Abstract A two-phase Newtonian surface fluid is modelled as a surface Cahn–Hilliard–Navier–Stokes equation using a stream function formulation. This allows one to circumvent the subtleties in

The Interplay of Curvature and Vortices in Flow on Curved Surfaces

Motivated by designed examples for superfluids, the influence of a geometric potential on vortices for fluids with finite viscosity is considered and numerical examples in which a change in the geometry is used to manipulate the flow field are shown.

Stable numerical approximation of two-phase flow with a Boussinesq-Scriven surface fluid

We consider two-phase Navier–Stokes flow with a Boussinesq–Scriven surface fluid. In such a fluid the rheological behaviour at the interface includes surface viscosity effects, in addition to the

Hydrodynamic interactions in polar liquid crystals on evolving surfaces

We consider the derivation and numerical solution of the flow of passive and active polar liquid crystals, whose molecular orientation is subjected to a tangential anchoring on an evolving curved

On singular limit equations for incompressible fluids in moving thin domains

We consider the incompressible Euler and Navier-Stokes equations in a three-dimensional moving thin domain. Under the assumption that the moving thin domain degenerates into a two-dimensional moving

Solving the incompressible surface Navier-Stokes equation by surface finite elements

We consider a numerical approach for the incompressible surface Navier-Stokes equation on surfaces with arbitrary genus g(S). The approach is based on a reformulation of the equation in Cartesian

Incompressible fluid problems on embedded surfaces: Modeling and variational formulations

Governing equations of motion for a viscous incompressible material surface are derived from the balance laws of continuum mechanics. The surface is treated as a time-dependent smooth orientable

Divergence‐free tangential finite element methods for incompressible flows on surfaces

This work considers the numerical solution of incompressible flows on two‐dimensional manifolds and presents several new finite element discretizations, including H(divΓ) ‐conforming finite elements can be used to obtain exactly divergence‐free velocity solutions.
