دانلود کتاب لایه های برشی آشفته در جریان مافوق صوت Turbulent Shear Layers in Supersonic Flow

The aims of this book are to bring together the most recent results on the behavior
of turbulent boundary layers at supersonic speed and to present some
conclusions regarding our present understanding of these flows. By doing so,
we hope to give the reader a general introduction to the field, whether they be
students or practicing research engineers and scientists, and to help provide a
basis for future work in this area. Most textbooks on turbulence or boundary
layers contain some background on turbulent boundary layers in supersonic
flow, but the information is usually rather cursory, or it is out of date. Only
one, by Kutateladze and Leont’ev (1964), addresses the specific issue of turbulent
boundary layers in compressible gases, but it focuses largely on solutions
of the integral equations of motion, and it is not much concerned with the turbulence
itself. Some aspects of turbulence are addressed by Cousteix (1989),
but only one chapter is devoted to this topic, and his review, although very
useful, is not exhaustive. The scope of the present book is considerably wider
in that we are concerned with physical descriptions of turbulent shear-layer
behavior, and the response of the mean flow and turbulence to a wide variety
of perturbations. For example, in addition to turbulent mixing layers, we will
consider boundary layers on flat plates, with and without pressure gradient,
on curved walls, and the interaction of boundary layers with shock waves, in
two and three dimensions.

دانلود کتاب مقدمه ای بر جریان ماوراء صوت Introduction to Hypersonic flow

Although other books in the field of hypersonic flow are now published
in EngUsh, it was felt that this book should be made available to
the Enghsh speaking reader because of its usefulness for those individuals
desirous of obtaining an introduction to the subject. Except for
a general introductory chapter the book concentrates on the inviscid,
perfect fluid aspects of hypersonic flow, with emphasis on the fundamental
concepts and rational methods of calculation. The book is
directed to students of aerodynamics and gasdynamics, as well as to
scientists and engineers interested in problems of hypersonic flight. The
level of approach is such that it should prove particularly useful as an
undergraduate and introductory graduate text.

دانلود کتاب MICRO-CHP POWER GENERATION FOR RESIDENTIAL AND SMALL COMMERCIAL BUILDINGS

Micro-cooling, heating, and power (micro-CHP) is decentralized electricity
generation coupled with thermally activated components for residential and small
commercial applications. A micro-CHP system consists of a prime mover, such as
a reciprocating engine, which drives a generator, which produces electrical power.
The waste heat from the prime mover is recovered and used to drive thermally
activated components and to produce hot water or warm air through the use of
heat exchangers.

دانلود کتاب سوختهای زیستی و نقل و انتقال جاده ای Biofuels for Road Transport

This book will give a seed-to-wheel perspective on biofuels for road transport and
will deal with a number of environmental issues that have emerged in the current
biofuel debate. This first chapter is introductory and structured as follows: firstly,
Sects. 1.2–1.6 will deal with the physical basis and the variety of biofuels and the
ways to produce and apply them in transport. Secondly, in Sect. 1.7, developments
in production volume, costs and prices will be discussed. Thereafter, in Sect. 1.8, the
debate on the pros and cons of transport biofuels that has emerged will be briefly
surveyed, and the rest of the book will be outlined.
