Boundary conditions at a fluid-solid interface.
We study the boundary conditions at a fluid-solid interface using molecular dynamics simulations covering a broad range of fluid-solid interactions and fluid densities and both simple and chain-molecule fluids. The slip length is shown to be independent of the type of flow, but rather is related to the fluid organization near the solid, as governed by the fluid-solid molecular interactions.
متن کاملMoving Three Collinear Griffith Cracks at Orthotropic Interface
This work deals with the interaction of P-waves between a moving central crack and a pair of outer cracks situated at the interface of an orthotropic layer and an elastic half-space. Initially, we considered a two-dimensional elastic wave equation in orthotropic medium. The Fourier transform has been applied to convert the basic problem to solve the set of four integral equations. These set of ...
متن کامل0 Boundary conditions at a fluid – solid interface
The principal theme of this paper is a study of the nature of the boundary conditions (BC) of fluid flow past a solid surface, a crucial ingredient in any continuum fluid mechanical calculation. The BC cannot be deduced from the continuum differential equations themselves, and it is often not easy to determine them experimentally. While the normal component of the fluid velocity must vanish at ...
متن کاملConvection in a Tilted Square Enclosure with Various Boundary Conditions and Having Heat Generating Solid Body at its Center
In this study free convection flow and heat transfer of a fluid inside a tilted square enclosure having heat conducting and generating solid body positioned in the center of the enclosure with various thermal boundary conditions has been investigated numerically. The governing equations are transformed into non-dimensional form and the resulting partial differential equations are solved by Fini...
متن کاملTECHNISCHE UNIVERSITÄT BERLIN Moving Dirichlet Boundary Conditions
This paper develops a framework to include Dirichlet boundary conditions on a subset of the boundary which depends on time. In this model, the boundary conditions are weakly enforced with the help of a Lagrange multiplier method. In order to avoid that the ansatz space of the Lagrange multiplier depends on time, a bi-Lipschitz transformation, which maps a fixed interval onto the Dirichlet bound...
