A monolithic fluid-structure interaction formulation for solid and liquid membranes including free-surface contact
A unified fluid-structure interaction (FSI) formulation is presented for solid, liquid and mixed membranes. Nonlinear finite elements (FE) and the generalized-α scheme are used for the spatial and temporal discretization. The membrane discretization is based on curvilinear surface elements that can describe large deformations and rotations, and also provide a straightforward description for con...
متن کاملLiquid Droplet in Contact with a Solid Surface
A liquid droplet in contact with a solid surface was simulated by the molecular dynamics method, in order to study the microscopic aspects of the liquid-solid contact phenomena and phase change heat transfer. Measured ‘contact angle’ was well correlated by the depth of the integrated potential of the surface. The layered liquid structure near the surface was also explained with the integrated p...
متن کاملA computational formulation for constrained solid and liquid membranes considering isogeometric finite elements
A geometrically exact membrane formulation is presented that is based on curvilinear coordinates and isogeometric finite elements, and is suitable for both solid and liquid membranes. The curvilinear coordinate system is used to describe both the theory and the finite element equations of the membrane. In the latter case this avoids the use of local cartesian coordinates at the element level. C...
متن کاملA symmetric positive definite formulation for monolithic fluid structure interaction
In this paper we consider a strongly coupled (monolithic) fluid structure interaction framework for incompressible flow, as opposed to a loosely coupled (partitioned) method. This requires solving a single linear system that combines the unknown velocities of the structure with the unknown pressures of the fluid. In our previous work, we were able to obtain a symmetric formulation of this coupl...
متن کاملWater-solid surface contact electrification and its use for harvesting liquid-wave energy.
Contact electrification, also called triboelectrification, is an old but well-known phenomenon in which surface charge transfer occurs when two materials are brought into contact. Although some of the fundamental mechanisms about triboelectrification are still under discussion, such as what subjects (electrons, ions, or small amounts of material) are transferred during the contact and separatio...
