The closed form expressions of the effective properties in periodic fluid laminates are derived thanks to Padé approximation transfer matrix. A second-order Taylor expansion matrix elements exhibits Willis coupling. This coupling is sum a local term and nonlocal term. arises from apparent bulk modulus quasi one-dimensional problems. nonlocality directly impacts governing equations modeling acou...

The liquid cargo contained in a partly-filled road tank vehicle is prone to dynamic slosh movement when subjected to external disturbances. The slosh behavior has been identified as a significant factor impairing the safety of liquid cargo transportation. The laboratory experiments have been conducted for analyzing fluid slosh in partly filled tanks. The experiment results measured under forced...

Abstract. The dynamics of a membrane is a coupled system of a moving elastic surface and an incompressible membrane fluid. The difficulties in analyzing such a system include the nonlinearity of the curved space (geometric nonlinearity), the nonlinearity of the fluid dynamics (fluid nonlinearity), and the coupling to the surface incompressibility. In the two-dimensional case, the fluid vanishes...

Structure and fluid models need to be combined, or coupled, when problems of fluidstructure interaction (FSI) are addressed. We first present the basic knowledge required for building and then evaluating a simple coupling. The approach proposed is to consider a dedicated solver for each of the two physical systems involved. We illustrate this approach by examining the interaction between a gas ...

We propose a computational method for the coupled simulation of a compressible flow interacting with a thin-shell structure undergoing large deformations. An Eulerian finite volume formulation is adopted for the fluid and a Lagrangian formulation based on subdivision finite elements is adopted for the shell response. The coupling between the fluid and the solid response is achieved via a novel ...

A 1D/3D Finite-Volume coupling is proposed for the Euler/Homogeneous Equilibrium Model equations. The present approach based on framework making it possible to tackle general equations of state . special attention given conservation mass , momentum and energy at common interface. For fluid–structure interaction induced by fast-transient phenomena occurring in pipelines, fluid also associated wi...

In this paper we seek to relate the influence of the geometry and distribution of fracture aperture to the fluid flow properties of the fracture. Coupling fluid flow and transport experiments to high-resolution laser scanning confocal microscopy (LSCM) enables tracking of local fluid velocity and particle trajectories, and allows direct quantification of variations caused by surface roughness. ...
