On the asymptotical behaviour for $t\to\infty$ of solutions of initial boundary-value problems for the equations of motions of linear viscoelastic fluids
A. P. Oskolkov
Abstract:
It is proved that for nonstationary equations of motions of
linear viscoelastic fluids which obey the reological equation
$$
\left(1+\sum_{l=1}^L\lambda_l\frac{\partial^l}{\partial t^l}\right)\sigma=2\nu\left(1+\sum_{m=1}^M x_m\nu^{-1}\frac{\partial^m}{\partial t^m}\right)D,
$$
the stationary system is the stationary Navier–Stokes system
$$
-\nu\Delta v+v_k\frac{\partial v}{\partial x_k}+\mathrm{grad}\, p=f(x), \quad\mathrm{div}\, v=0.\qquad{(*)}
$$
It is proved that for “small” Reynolds numbers solutions of
the initial boundary-value problems for the equations of motions
of Oldroyd type fluids ($M=L=1,2,\dots$) and Kelvin–Voight type fluids
($M=L+1$, $L=0,1,2,\dots$) fends for $t\to\infty$ to the solution of the
boundary-value problem for the stationary Navier–Stokes system ($*$).
