Thin, flexible, continuous structures known as webs are used in a wide range of industrial applications. These structures interact with the surrounding air in beneficial or detrimental ways, depending on the application and the process parameters. A review of the literature related to modeling and experimental work on (mostly) the steady state fluid-structure interactions is given. Equilibrium ...

A density functional study of the structure of a layer formed by chain molecules pinned to a solid surface is presented. The chains are modeled as freely joined spheres. Segments and all components interact via LennardJones (12–6) potential. The interactions of fluid molecules with the wall are described by the Lennard-Jones (9–3) potential. We analyze how different parameters of the model affe...

We present an algorithm for modelling coupled dynamic interactions of a very thin flexible structure immersed in a high-speed flow. The modelling approach is based on combining an Eulerian finite volume formulation for the fluid flow and a Lagrangian large-deformation formulation for the dynamic response of the structure. The coupling between the fluid and the solid response is achieved via an ...

The immersed boundary method is both a mathematical formulation and a numerical method for the study of fluid structure interactions. Many numerical schemes have been introduced to reduce the difficulties related to the non-linear coupling between the structure and the fluid evolution; however numerical instabilities arise when explicit or semi-implicit methods are considered. In this work we p...

The immersed boundary method is both a mathematical formulation and a numerical method. In its continuous version it is a fully non-linearly coupled formulation for the study of fluid structure interactions. As it is common in these cases, many numerical methods have been introduced to reduce the difficulties related to the non-linear coupling between the structure and the fluid evolution, howe...

Background: In the last decades, mesoporous silica nanoparticles (MSN) are improved for drug delivery, imaging, and biomedical applications due to their special properties such as large surface area, high drug loading capacity, tunable pore size, and modification of surface area by functional groups. Objectives: The aim of this study was to evaluate MSNs as carriers for oral colon-specific and...

In this study, the effect of small-scale of both nanostructure and nano-fluid flowing through it on the natural frequency and longitudinal wave propagation are investigated. Here, the stationary and axially moving single-walled carbon nanotube conveying fluid are studied. The boundary conditions for the stationary nanotube is considering clamped-clamped and pined-pined and for the axially movin...
