Steady Viscous Flow with Fractal Power Spectrum.
We demonstrate a family of two-dimensional steady viscous flows which have singular continuous (fractal) Fourier spectra. Such flows represent a novel intermediate stage between order and Lagrangian chaos: The motion of individual fluid particles in them is neither entirely correlated nor completely disordered. In the considered setup these flows are presented by the exact solutions of the Navi...
متن کاملSteady-state tensile viscous flow forming of bulk metallic glass
Tensile viscous flow is explored as a forming method for metallic glasses in their supercooled liquid temperature region. Bulk amorphous preforms with nominal alloy composition Zr55Cu30Al10Ni5 were produced by arc melting and tiltand suction casting into a copper mould. A simple loading rig, in which the preform is suspended from a wire, combined with selective heating of the section to be defo...
متن کاملSteady-state Buoyancy-driven Viscous Flow with Measure Data
Abstract. Steady-state system of equations for incompressible, possibly non-Newtonean of the p-power type, viscous flow coupled with the heat equation is considered in a smooth bounded domain Ω ⊂ n , n = 2 or 3, with heat sources allowed to have a natural L1structure and even to be measures. The existence of a distributional solution is shown by a fixed-point technique for sufficiently small da...

متن کاملFine Grid Numerical Solutions of Triangular Cavity Flow
Numerical solutions of 2-D steady incompressible flow inside a triangular cavity are presented. For the purpose of comparing our results with several different triangular cavity studies with different triangle geometries, a general triangle mapped onto a computational domain is considered. The Navier-Stokes equations in general curvilinear coordinates in streamfunction and vorticity formulation...
