Multiscale Models for Flow in Heterogeneous Media with Applications to Fresh Concrete

Original language description

The chapter presents a state-­of-­the art review of available multiscale methods in the area of heterogeneous media flows with application to fresh concrete flow and particularly how the effect of traditional reinforcement can be taken into account. First, it will be shown how the Darcy law can be derived from the homogenization of stationary Navier-­Stokes system. Later, we provide an overview of generalization of this result to non-Newtonian fluids, as the fresh concrete can on macroscale considered as non-Newtonian fluid. In the last part, the results of modeling the effect of reinforcing bars in the single-­fluid approach by means of computational homogenization are presented.
