- Existence and large time behavior for generalized Kelvin-Voigt equations governing nonhomogeneous and incompressible fluidsPublication . Antontsev, S N; de Oliveira, H. B.; Khompysh, KhGeneralized Kelvin-Voigt equations governing nonhomogeneous and incompressible fluids are considered in this work. We assume that, in the momentum equation, the diffusion and relaxation terms are described by two distinct power-laws. Moreover, we assume that the momentum equation is perturbed by an extra term, which, depending on whether its signal is positive or negative, may account for the presence of a source or a sink within the system. For the associated initial-boundary value problem, we study the existence of weak solutions as well as the large time behavior of the solutions.
