This is the first book to present a model, based on rational mechanics
of electrorheological fluids, that takes into account the complex
interactions between the electromagnetic fields and the moving liquid.
Several constitutive relations for the Cauchy stress tensor are
discussed. The main part of the book is devoted to a mathematical
investigation of a model possessing shear-dependent viscosities, proving
the existence and uniqueness of weak and strong solutions for the steady
and the unsteady case. The PDS systems investigated possess so-called
non-standard growth conditions. Existence results for elliptic systems
with non-standard growth conditions and with a nontrivial nonlinear
r.h.s. and the first ever results for parabolic systems with a
non-standard growth conditions are given for the first time. Written for
advanced graduate students, as well as for researchers in the field, the
discussion of both the modeling and the mathematics is self-contained.
