Four approaches to hydrodynamic Green’s functions - the Oseen tensors

چکیده

A very ’physical’ approach to this phenomenon can be made by making use of the linearity of Stokes equations and symmetries of the system. Here, we preform detailed calculations according to hints from Exercise 2.9 from the textbook [Kim & Karilla]. As the Stokes equations are linear in p and v, the pressure field p(r) can be written as a scalar product of a certain vector field P(r) and the point force F and the velocity field v(r) can be represented by a a tensor G(r) acting on a point force F with certain factors:

Three-Dimensional Interfacial Green’s Function for Exponentially Graded Transversely Isotropic Bi-Materials

By virtue of a complete set of two displacement potentials, an analytical derivation of the elastostatic Green’s functions of an exponentially graded transversely isotropic bi-material full-space was presented. Three-dimensional point-load Green’s functions for stresses and displacements were given in line-integral representations. The formulation included a complete set of transformed stress-p...

From the initial time dependence of the dynamic structure factor S{k,t), we obtain a general form, valid through second order in the concentration, for the mutual diffusion coefficient J) m' All effects of direct and hydrodynamic interactions (other than dynamic friction) are taken into account, including the three-point "Oseen" hydrodynamic tensor Tij" whose analytic form is obtained here for ...

Nonsingular Green’s Functions for Multi-Layer Homogeneous Microstrip Lines

In this article, three new green's functions are presented for a narrow strip line (not a thin wire) inside or on a homogeneous dielectric, supposing quasi-TEM dominant mode. These functions have no singularity in contrast to so far presented ones, so that they can be used easily to determine the capacitance matrix of multi-layer and single-layer homogeneous coupled microstrip lines. To obtain ...

Short Note Surface-Wave Green’s Tensors in the Near Field

We demonstrate the connection between theoretical expressions for the correlation of ambient noise Rayleigh and Love waves and the exact surface-wave Green’s tensors for a point force. The surface-wave Green’s tensors are well known in the far-field limit. On the other hand, the imaginary part of the exact Green’s tensors, including near-field effects, arises in correlation techniques such as t...

Real-space Green’s tensors for stress and strain in crystals with cubic anisotropy

Real-space Green’s tensors are presented for the calculation of the stress or strain in infinite cubic crystals containing buried quantum wires or dots of arbitrary shape and composition, including the cubic anisotropy of elastic constants. The Green’s tensors are obtained as a polynomial series to second order in , an expansion coefficient defined in terms of the elastic stiffnesses. The zerot...
