Abstract It is observed that the feather surface exhibits anisotropic resistances for streamwise and spanwise flows. To obtain a qualitative understanding about effect of this resistance feature on boundary-layer transitional flow over flat plate, simple phenomenological model established in paper. By means large eddy simulation (LES) with high-order accurate finite difference method, numerical...

In this study, a numerical examination of the significance of rotation and changeable gravitational field on the start of nanofluid convective movement in an anisotropic porous medium layer is shown. A model that accounts for the impact of Brownian diffusion and thermophoresis is used for nanofluid, while Darcy’s law is taken for the porous medium. The porous layer is subjected to uniform rotat...

Reflectivity synthetic seismograms demonstrate that the type, layering and orientation of 1-D anisotropy influences strongly the coda of teleseismic P waves at periods T\1 sec, particularly P-SH converted waves. We assume the simplest form of anisotropy described by an elastic tensor with a symmetry axis ŵ of arbitrary orientation. The resulting phase velocities vary as cos 2j with respect to t...

A new approach to model and compute the metric tensor corresponding a-priori prescribed surface volume boundary layers is presented. This achieved by use of sources that combined anisotropic metric. Algorithms are presented both evaluate resulting value at any point in space efficient approximation minimum maximum over an axis-aligned box which enables fast evaluation independent used for mesh ...
