Nonlinear Optics and Laser Emission through Random Media

Nonlinear Optics and Laser Emission through Random Media PDF Author: Viola Folli
Publisher: Springer Science & Business Media
ISBN: 9400745133
Category : Technology & Engineering
Languages : en
Pages : 122

Book Description
Disorder is everywhere, inherently present in nature, and is commonly believed to be a synonymous with disturbance. As a consequence, the methodical and customary study of the dynamics of the electromagnetic field, both in the linear and nonlinear optical regimes, leans to rule out it from the treatment. On the other hand, nonlinearity enriches the physical disciplines and brings them closer to reality with respect to the linear approximation. Nonlinearity allows to stimulate a wide and rich ensemble of optical responses that beautifies the role of matter in the active processes with electromagnetic fields. Independently of each other, both of these mechanisms foster localization of light. What happens when light enlightens their synergistic interaction? When pushed together, light, disorder and nonlinearity make new and intriguing phenomena emerge. This text provides a comprehensive investigation of the role of disorder in the nonlinear optical propagation both in transparent media and lasers. Eventually, disorder promotes and enhances complex nonlinear dynamics opening new perspectives in applied research driven by the processes of localization of the electromagnetic field. The first experimental study of laser emission in granular media unveils how randomness magnifies and largely affect laser-matter interactions. Viola Folli in her research work touches and deepens the leading milestones of the new science named Complex Photonics.

Upscaling of Single- and Two-Phase Flow in Reservoir Engineering

Upscaling of Single- and Two-Phase Flow in Reservoir Engineering PDF Author: Hans Bruining
Publisher: CRC Press
ISBN: 1000463273
Category : Technology & Engineering
Languages : en
Pages : 239

Book Description
- Explains exergy return on exergy invested (ERoEI) so that the reader can make his own judgements as to the costs of recovering energy from conventional and non-conventional resources - Deals with single phase flow aspects (inertia, anisotropy, slip), which admittedly are covered in other textbooks, but out of the contexts of petroleum and environmental engineering. - Gives readers the tools to generate heterogeneous permeability fields (stochastic random fields, marked point processes, Markov chains, which makes it possible to evaluate the effects of heterogeneity on flow - Includes an elaborate section on surface chemistry to understand wetting behaviour and its influence on the relative permeability and capillary pressure behaviour - Derives effective permeabilities and relative permeabilities in upscaled models and illustrates this with examples in EXCEL

Applied RVE Reconstruction and Homogenization of Heterogeneous Materials

Applied RVE Reconstruction and Homogenization of Heterogeneous Materials PDF Author: Yves Rémond
Publisher: John Wiley & Sons
ISBN: 1119307570
Category : Technology & Engineering
Languages : en
Pages : 212

Book Description
Applied RVE Reconstruction and Homogenization of Heterogeneous Materials Statistical correlation functions are a well-known class of statistical descriptors that can be used to describe the morphology and the microstructure-properties relationship. A comprehensive study has been performed for the use of these correlation functions for the reconstruction and homogenization in nanocomposite materials. Correlation functions are measured from different techniques such as microscopy (SEM or TEM), small angle X-ray scattering (SAXS) and can be generated through Monte Carlo simulations. In this book, different experimental techniques such as SAXS and image processing are presented, which are used to measure two-point correlation function correlation for multi-phase polymer composites. Higher order correlation functions must be calculated or measured to increase the precision of the statistical continuum approach. To achieve this aim, a new approximation methodology is utilized to obtain N-point correlation functions for multiphase heterogeneous materials. The two-point functions measured by different techniques have been exploited to reconstruct the microstructure of heterogeneous media. Statistical continuum theory is used to predict the effective thermal conductivity and elastic modulus of polymer composites. N-point probability functions as statistical descriptors of inclusions have been exploited to solve strong contrast homogenization for effective thermal conductivity and elastic modulus properties of heterogeneous materials. Finally, reconstructed microstructure is used to calculate effective properties and damage modeling of heterogeneous materials.

Capillary Flows in Heterogeneous and Random Porous Media

Capillary Flows in Heterogeneous and Random Porous Media PDF Author: Rachid Ababou
Publisher: John Wiley & Sons
ISBN: 111876210X
Category : Technology & Engineering
Languages : en
Pages : 359

Book Description
Capillary phenomena occur in both natural and human-made systems, from equilibria in the presence of solids (grains, walls, metal wires) to multiphase flows in heterogeneous and fractured porous media. This book, composed of two volumes, develops fluid mechanics approaches for two immiscible fluids (water/air or water/oil) in the presence of solids (tubes, joints, grains, porous media). Their hydrodynamics are typically dominated by capillarity and viscous dissipation. This first volume presents the basic concepts and investigates two-phase equilibria, before analyzing two-phase hydrodynamics in discrete and/or statistical systems (tubular pores, planar joints). It then studies flows in heterogeneous and stratified porous media, such as soils and rocks, based on Darcy’s law. This analysis includes unsaturated flow (Richards equation) and two-phase flow (Muskat equations). Overall, the two volumes contain basic physical concepts, theoretical analyses, field investigations and statistical and numerical approaches to capillary-driven equilibria and flows in heterogeneous systems
