Optimal error estimate for semi-implicit space-time discretization for the equations describing incompressible generalized Newtonian fluids
No full textIn this paper we study the numerical error arising in space-time approximation of unsteady power-law non-Newtonian fluids. A semi-implicit time discretization scheme, coupled with space discretization made with conforming finite elements is analyzed. The main result, which improves previous suboptimal estimates as those in [A.~Prohl, and M.~Ruzicka, SIAM J. Numer. Anal., 39 (2001), pp.~214--249] is the optimal O(k+h) error-estimate valid in the wide range pin]3/2,2], where k is the time-step and h the mesh-size.
Our results hold in three-dimensional domains (with periodic boundary conditions), are uniform with respect to the degeneracy parameter delta of the extra stress tensor, and a stability h-k-coupling depending on p is also needed

Global L^r -estimates and regularizing effect for solutions to the p(t,x)-Laplacian systems
No full textWe consider the initial boundary value problem for the p(t,x)-Laplacian system in a bounded domain. If the initial data belongs to L^{r_0}, r_0≥2, we prove a global L^{r_0}-regularity result uniformly in t>0 that, in the particular case r_0=infty, gives a maximum modulus theorem. Under the assumption p−=inf p(t,x)>2n/(n+r_0), we also study L^{r_0}−L^r estimates for the solution, for r≥r_0

Swelling of responsive-microgels: experiments versus models
No full textInterpenetrated Polymer Network (IPN) microgels of PNIPAM and PAAc have been investigated and the experimental data have been compared with theoretical models from the Flory–Rehner theory. We confirm that the swelling behavior of PNIPAM microgels is well described by this theory by considering the second order approximation for the volume fraction φ dependence of the Flory parameter χ(φ). Indeed the Volume-Phase Transition (VPT) of the PNIPAM-PAAc IPN microgel at neutral conditions and in D2O solvents can be well described only considering a third-order approximation. Interestingly we empirically find that sharper is the transition higher is the order of the χ(φ) relation which has to be considered. Moreover the VPT can be experimentally controlled by tuning the polymer/solvent interactions through pH and solvent allowing to directly modify the delicate balance between energetic and entropic contributions and to explore the swelling behavior in a wide range of environmental conditions. In particular we find that the most advantageous condition for swelling is in water at acidic pH
