On extension and torsion of a compressible elastic circular cylinder

, 2002
In this paper we examine the combined extension and torsion of a compressible isotropic elastic cylinder of finite extent. The equilibrium equations are formulated in terms of the principal stretches and then applied to the special case of pure torsion ...

Sustainable Nonwoven Triboelectric Nanogenerator Including Pseudo‐Thickness Enabled Consistent Power Generation in Ultralow Contact Frequency

Small Structures
A poly(ethylene terephthalate) (PET) nonwoven‐fabric‐based triboelectric nanogenerator (NWF‐TENG) with high energy‐harvesting efficiency at ultralow contact frequencies is introduced, enabled by the concept of pseudo‐thickness.

Large-eddy simulation of the compressible flow past a wavy cylinder

, 2010
Numerical investigation of the compressible flow past a wavy cylinder was carried out using large-eddy simulation for a free-stream Mach number M? = 0.75 and a Reynolds number based on the mean diameter Re = 2 × 105.

Numerical simulation of weakly compressible multi-material flows [PDF]

, 2018
International audienceIn this talk, we propose an implicit relaxation scheme for the simulation of weakly compressible multi-material flows. We adopt a monolithic Eulerian model describing gases, fluids and elastic solids with the same system of ...

Effects of Material Moduli on Compressible Fluid-Solid Systems Using Implicit Immersed Continuum Methods

, 2008
Using a compressible fluid-solid test system, we would like to illustrate the need for implicit immersed continuum method. The implicit mixed finite element formulation for both solid and fluid domains solves the volume conservation problem associated ...

Error estimation and adjoint-based adaptation in aerodynamics [PDF]

, 2006
In this article we give an overview of recent developments in error estimation and in residual-based and goal-oriented (adjoint-based) adaptation for Discontinuous Galerkin discretizations of sub- and supersonic viscous compressible flows.
