Book Description
This book - a sequel of previous publications 'Flows and Chemical Reactions' and 'Chemical Reactions in Flows and Homogeneous Mixtures' - is devoted to flows with chemical reactions in heterogeneous environments. Heterogeneous media in this volume include interfaces and lines. They may be the site of radiation. Each type of flow is the subject of a chapter in this volume. We consider first, in Chapter 1, the question of the generation of environments biphasic individuals: dusty gas, mist, bubble flow. Chapter 2 is devoted to the study at the mesoscopic scale: particle-fluid exchange of momentum and heat with determination of the respective exchange coefficients. In Chapter 3, we establish simplified equations of macroscopic balance for mass, for the momentum and energy, in the case of particles of one size (monodisperse suspension). Radiative phenomena are presented in Chapter 5.

Book Description
The International Symposium on Biological Effects of Magnetic and Electrom- netic Fields was held from September 3-4, 1993 at Kyushu University in Fukuoka . Japan . Originally, it was only intended to be an informal gathering of many scientists who had accepted my invitation to visit Kyushu University after the XXIVth General Assembly of the International Union of Radio Science (URSI), held in Kyoto prior to our symposium . However, since so many distinguished scientists were able to come, it was decided that a more formal symposium would be possible . It was a very productive symposium and, as a result, many of the guests consented that it would be a good idea to gather all the information put forth at the meeting and have it published. In addition, although they were unfortunately unable to attend the symposium . many other distinguished scientists had also expressed their wish to contribute to this effort and, in so doing. help to increase understanding in this, as yet, relatively immature field of science . The question of both positive and negative effects of magnetic and electromagnetic fields on biological systems has become more and more important in our world today as they .

Book Description
This concise text, first published in 2003, is for a one-semester course for upper-level undergraduates and beginning graduate students in engineering, science, and mathematics, and can also serve as a quick reference for professionals. The major topics in ordinary differential equations, initial value problems, boundary value problems, and delay differential equations, are usually taught in three separate semester-long courses. This single book provides a sound treatment of all three in fewer than 300 pages. Each chapter begins with a discussion of the 'facts of life' for the problem, mainly by means of examples. Numerical methods for the problem are then developed, but only those methods most widely used. The treatment of each method is brief and technical issues are minimized, but all the issues important in practice and for understanding the codes are discussed. The last part of each chapter is a tutorial that shows how to solve problems by means of small, but realistic, examples.

Book Description
Dimensional analysis is the basis for the determination of laws that allow the experimental results obtained on a model to be transposed to the fluid system at full scale (a prototype). The similarity in fluid mechanics then allows for better redefinition of the analysis by removing dimensionless elements. This book deals with these two tools, with a focus on the Rayleigh method and the Vaschy-Buckingham method. It deals with the homogeneity of the equations and the conversion between the systems of units SI and CGS, and presents the dimensional analysis approach, before addressing the similarity of flows. Dimensional Analysis and Similarity in Fluid Mechanics proposes a scale model and presents numerous exercises combining these two methods. It is accessible to students from their first year of a bachelorÂs degree.

Book Description
Interfaces are present in most fluid mechanics problems. They not only denote phase separations and boundary conditions, but also thin flames and discontinuity waves. Fluid Mechanics at Interfaces 1 focuses on the science of interfaces, in particular, using various scientific methods of analysis relating to space, speed and time. Our investigation takes us from the microscopic or small scale (starting with molecular and nanoscopic scales) to the macroscopic (including meso and interstellar scales), and also explores the laws of interfaces (classical mechanics, quantum mechanics and relativistic mechanics). Chapter 1 examines the questions raised by modeling interfaces in the presence of one or more fluid phases. Chapter 2 discusses the action of turbulence in liquid–vapor flows that contain both small, dispersed bubbles as well as large bubbles, with heat exchanges at the interfaces. In addition, a new model is presented, using large eddy simulation (LES). Chapter 3 studies an original method for calculating the drag force and thermal transfers in flows around networks of spherical particles, while Chapter 4 focuses on the relationships between interfaces and critical fluids. Chapter 5 examines shearing, which causes anomalies in the Brownian motion of particles in strongly fluctuating near-critical mixtures, and Chapter 6 introduces basic concepts related to combustion interfaces, raising the question of the combustion of solids, before ending with a brief presentation of the Rankine–Hugoniot theory and a historical overview of the research carried out in the field of combustion.

Book Description
The enhancement to laminar, non-premixed flames by the application of an external electric field is studied. It has long been known that naturally occurring ions are produced through chemical reactions during the combustion of hydrocarbon flames. Chemi-ionization has been noted in the literature as the source of naturally occurring flame ions and electrons. Because chemi-ions exist in very small quantities within the flame (109--10 10 ions/cm3), they contribute very little to the overall natural combustion process and can usually be neglected in conventional combustion applications/studies. However, with the application of an external electric field, the chemi-ions/electrons can have a dramatic effect on combustion through ion driven winds.Ion current measurements are characterized for conical-type methane flames stabilized on axially symmetric burners with longitudinal electric fields applied. The ion currents are used to correlate the flux of chemi-ions to measured flame characteristics. The manipulation of the flame by ion winds is analyzed through CH* chemiluminescence where flame geometry and light emission are the main targets to be studied. The modification to the thermal flow field is analyzed through schlieren imagery. The visualization through schlieren demonstrates how ion winds enhance the exhaust gas and provides a means of analyzing the interaction between ion fluxes and surrounding neutral flow. Numerical CFD models are described and validated. Ion wind body forces are generalized to simple body forces to test the extent to which ion winds can be used to describe the experimental observations. The numerical models provide a means of studying more in-depth complicated interactions of the flame and gaseous flows to enhanced body forces. Finally, a theoretical model is developed which highlights the important mechanisms involved in the modification of flame and gas flow dynamics by body forces due to gravity and external electric fields.Ion winds are shown to be the dominant mechanism in external electric field enhanced combustion. Ion winds explain nearly all of the observed effects on flames by external fields. The relatively small disparities that do exist between the experimental results and numerical results are likely from the uncertainties associated with chemical kinetics of minor species with extremely small concentrations and the use of simplified transport in the simulation.
