Numerical Modeling of Nanoparticle Transport in Porous Media: MATLAB/PYTHON Approach focuses on modeling and numerical aspects of nanoparticle transport within single- and two-phase flow in porous media. The book discusses modeling development, dimensional analysis, numerical solutions and convergence analysis. Actual types of porous media have been considered, including heterogeneous, fractured, and anisotropic. Moreover, different interactions with nanoparticles are studied, such as magnetic nanoparticles, ferrofluids and polymers. Finally, several machine learning techniques are implemented to predict nanoparticle transport in porous media. This book provides a complete full reference in mathematical modeling and numerical aspects of nanoparticle transport in porous media. It is an important reference source for engineers, mathematicians, and materials scientists who are looking to increase their understanding of modeling, simulation, and analysis at the nanoscale.

Fractional Modeling of Fluid Flow and Transport Phenomena

Fractional Modeling of Fluid Flow and Transport Phenomena

Fractional Modeling of Fluid Flow and Transport Phenomena focuses on mathematical and numerical aspects of fractional-order modeling in fluid flow and transport phenomena. The book covers fundamental concepts, advancements, and practical applications, including modeling developments, numerical solutions, and convergence analysis for both time and space fractional order models. Various types of flows are explored, such as single- and multi-phase flows in porous media, involving different fluid types like Newtonian, non-Newtonian, nanofluids, and ferrofluids. This book serves as a comprehensive reference on fractional-order modeling of fluid flow and transport phenomena, offering a single resource that is currently unavailable. Fractional-order modeling has gained traction in engineering and science, particularly in fluid dynamics and transport phenomena. However, its mathematical and numerical advancements have progressed relatively slowly compared to other aspects. Therefore, this book emphasizes the fractional-order modeling of fluid flow and transport phenomena to bridge this gap. Each chapter in the book delves into a specific topic closely related to the others, ensuring a cohesive and self-contained structure.

Introduction to The Quantum Theory of Matter and Radiation: Ethereal Universe

Introduction to The Quantum Theory of Matter and Radiation: Ethereal Universe

This revised edition narrates the brief history of the people, the events, and the ideas that advanced mankind into the electrical, nuclear, and space ages. The book describes the basic concepts of Quantum Mechanics and the efforts made to decipher the secrets of the structure of atoms, molecules, crystals and elementary nuclear particles. The author emphasizes the inherent limitations of classical mechanics that led to paradoxical outcome of the special theory of relativity, which in turn infected Dirac's attempts to rehabilitate the Schrodinger's Quantum Wave Equations. During the hundred and ten odd years of its existence, Quantum Mechanics has passed through three distinct stages of development. The first stage began by Planck's quanta and ended de Broglie's matter waves. It could be properly described as the stage of structuring the electronic shells of the atom. The second stage in the development of Quantum Mechanics began with de Broglie's discovery of matter waves, in 1924 and ended with the end of WWII. It could be properly described as the stage of deciphering the nuclear forces of the atomic core. The theory of the nucleus of the atom was created and new elementary particles were discovered that revealed some of the secrets of the nuclear forces. The third period began after World War II with the invention of nuclear reactors, radiospectrometers, and high altitude flights. This stage could be properly described as the phase of high energy exploration of the nuclear elementary particles. During this stage, Quantum Mechanics come up against ever greater difficulties, setbacks and failures. The newly discovered behaviors of elementary particles and their interactions shook the foundation of the old laws upon which Quantum Mechanics was erected.

This volume encompasses eight chapters from my personal study notes which cover all courses and notes in my study of Nuclear Engineering, from high school throughout my post-doctorate associateship. Great emphasis is added on the two theories of relativity where the author posed many critical questions regarding the optical definition of relative simultaneity which Einstein used to equate matter with energy through the relation E = mc .
