Analysis and Modelling of Physical Transport Phenomena

Analysis and Modelling of Physical Transport Phenomena



Analysis and Modelling of Physical Transport Phenomena
K. Hanjalic, S. Kenjeres, M.J. Tummers and H.J.J. Jonker

These lecture notes contain the material of the course Advanced Physical
Transport Phenomena, offered in the Master's programme in Applied Physics
at Delft University of Technology. The book aims at providing graduate
students with an overview of analytical, numerical and modelling methods
for solving problems of heat and fluid flow, following a unified and
comparative approach.
The material is divided into four parts. Part I overviews the conservation
laws for mass, momentum and energy in differential forms and the relevant
constitutive relations. Part II covers analytical methods for solving
generic problems of heat, mass and momentum transfer, aimed at providing
insight into the physics, as well as to encourage students to master the
analytical tools for gaining a physical intuition by solving problems in
idealized situations. Part III introduces numerical methods for
computer-aided solutions of complex problems that are not tractable by
analytical approaches. It is, in fact, an introduction into computational
fluid dynamics, heat and mass transfer (CFD, CHMT). Part IV deals with
turbulent convection. Basic notions on turbulence relevant to its
modelling are presented, followed by similarity and scaling analysis of
generic wall-bounded flows, the basics of turbulence modelling and an
overview of popular models, their physical rationale, interpretation and
limitations.

Electromagnetic waves - An Introductory Course

Electromagnetic waves appear in many forms and their applications are extremely widespread. Without exaggeration it may be said that our ability to employ and manipulate electromagnetic waves forms one of the reasons that communication plays such an important role in society.

The macroscopic theory of electromagnetic waves has been formulated by Maxwell in 1864. But the mathematical-physical nature of the subject makes it difficult for students to master even today. The continuous stream of new college textbooks shows that many teachers encounter this problem and attempt to resolve it by presenting the theory in some suitable form.

In the Electrical Engineering curriculum of the Delft University of Technology, the teaching of electromagnetic waves has been divided into three stages: 1) a basic course on Electricity and Magnetism, 2) an introductory course on Electromagnetic Waves, and 3) advanced courses on the application and computation of electromagnetic waves. The current book is written to facilitate the introductory course on Electromagnetic Waves. It is assumed that students are already acquainted with the basic phenomena and notions of the electric and the magnetic field, and that they know in which way Maxwell's equations describe the electromagnetic field. Starting from Maxwell's equations, this book deals with the derivation of plane wave propagation, plane wave reflection and transmission, electromagnetic rays, waves in two-wire transmission lines, waves in planar waveguides, and the excitation of electromagnetic waves. As such, the aim of the book is to provide a solid understanding of how the basic ingredients that make up the more sophisticated applications follow from Maxwell's equations.

The aim of the introductory course on Electromagnetic Waves is to teach students to manipulate the fundamental formulas in order to solve a problem at hand. To focus on this skill and to overcome the problem of having to learn many formulas by heart, an outline of this book is presented in the accompanying booklet entitled


Electromagnetic Waves -- A Repetitive Guide

Contents: Preface 1 Introduction 2 The Electromagnetic Field Equations 3 One-dimensional Electromagnetic Waves 4 Two-dimensional Electromagnetic Waves 5 Electromagnetic Rays in a Two-dimensional Medium 6 Transmission Lines 7 Electromagnetic Waveguides 8 Excitation of Two-dimensional Electromagnetic Waves Answers to Exercises Bibliography Index

Gravity does not exist

Gravity does not exist




Vincent Icke

Every scientific fact was born as an opinion about the unknown - a hypothesis. Opinion gradually becomes fact as evidence piles up to support a theory. But what if there are two theories, each of which has produced a myriad of things that correspond perfectly to the phenomena but can't be combined into one? One theory replaced the mystery of gravity with a precise model of space and time. The other theory replaced the mystery of matter with a description of quantum particles. As we understand our universe, we keep each in its own domain: space and time for very large things, particles for the very small ones. However, 13.8 billion years ago, those two incompatible domains belonged to a single realm. Who in the current or future generations of physicists will crack this seemingly impossible puzzle? This, contends the author, is not just a big question, but the biggest question in physics in our century. Combining Ickes's first-hand knowledge with a robust argument and intellectual playfulness, this fascinating book succeeds in making a notoriously difficult subject accessible to all readers interested in a better grasp of our universe. -Vincent Icke is professor of theoretical astrophysics at Universiteit Leiden, professor of cosmology at the University of Amsterdam, visual artist, and writer.
