    Exponential attractor for a planar shear-thinning flow

  • Original language description

    We study the dynamics of an incompressible, homogeneous fluid of a power-law type, with the stress tensor $TT=nu(1+mu |Dv|)^{p-2}Dv$, where $Dv$ is a symmetric velocity gradient. We consider the two-dimensional problem with periodic boundary conditions and $pin(1,2)$. Under these assumptions, we estimate the fractal dimension of the exponential attractor, using the so-called method of $ell$-trajectories.

    Exponenciální atraktor pro rovinné polynomiální proudění

  • Czech description

    Zabýváme se dynamikou nestlačitelné, homogenní tekutiny polynomiálního typu, kde tenzor napětí má tvar $TT=nu(1+mu |Dv|)^{p-2}Dv$, $Dv$ je symetrický gradient rychlosti. Uvažujeme 2d problém s periodickými okrajovými podmínkami a $pin(1,2)$. Za těchto předpokladů odhadneme explicitně dimenzi exponenciálního atraktoru, a to s použitím tzv. metody trajektorií.
