Abstract
Flow, transport, reaction, adsorption and deformation (FTRAD) constitute a fascinating set of phenomena that occur in a wide variety of porous media and materials over widely disparate length scales, from molecular, to pore, core, and field scales. In this presentation four classes of fundamental problems are described and the approaches to their modeling are discussed. We first describe a process-based modeling of fabrication of a nano-porous membrane based on quantum mechanical calculations and molecular dynamics simulations. We then outline a general approach to modeling of adsorption and swelling of several types of core-scale porous materials. Next, the problem of reconstruction of porous materials and media based on limited data, such as their two- or three-dimensional images is described, and a new method based on curvelet transforms for speeding up simulation of the FTRAD in such images is discussed. Finally, the problem of upscaling from core to field scale is described and a multiresolution approach to the problem based on wavelet transformations is discussed.
