"Showcases the beneftis and potential advantages of water
hydraulics over oil-based media. Interweaves examples and
excercises throughout the text to illustrate critical concepts,
with helpful appendices on abbreviations, symbols, conversion
factors, and water contaminants, and glossary sections."
The first of its kind, this modern, comprehensive text covers both analysis and design of piping systems. The authors begin with a review of basic hydraulic principles, with emphasis on their use in pumped pipelines, manifolds, and the analysis and design of large pipe networks. After the reader obtains an understanding of how these principles are implemented in computer solutions for steady state problems, the focus then turns to unsteady hydraulics. These are covered at three levels:
Reviewing basic fluid power principles, this updated Second Edition
presents practical methods for detecting, diagnosing, and
correcting fluid power problems within a system-detailing the
design, maintenance, and troubleshooting of pneumatic, hydraulic,
and electrical systems and components. Examines the root causes of
failures in items such as hydraulic pumps and motors, air motors,
hydraulic and pneumatic valves, compressors, accumulators, filters,
seals, cylinders, tubing, fittings, and hoses Fully revised and
expanded throughout, Fluid Power Troubleshooting, Second Edition
stresses the latest developments in understanding the complex
interactions of components within a fluid power system cartridge
valve systems, proportional valve and servo-systems, and compressed
air drying and filtering noise reduction and other environmental
concerns the control of contaminants in hydraulic and pneumatic
systems the selection and care of hydraulic system fluid the
reduction of leaks in fluid power systems and much more
This book describes the fundamental phenomena of, and computational
methods for, hydraulic transients, such as the self-stabilization
effect, restriction of the Joukowsky equation, real relations
between the rigid and elastic water column theories, the role of
wave propagation speed, mechanism of the attenuation of pressure
fluctuations, etc. A new wave tracking method is described in great
detail and, supported by the established conservation and traveling
laws of shockwaves, offers a number of advantages. The book puts
forward a novel method that allows transient flows to be directly
computed at each time node during a transient process, and explains
the differences and relations between the rigid and elastic water
column theories. To facilitate their use in hydropower
applications, the characteristics of pumps and turbines are
provided in suitable forms and examples. The book offers a valuable
reference guide for engineers and scientists, helping them make
transient computations for their own programming, while also
contributing to the final standardization of methods for transient
computations.
The use of hydraulic control is rapidly growing and the objective of this book is to present a rational and well-balanced treatment of its components and systems. Coverage includes a review of applicable topics in fluid mechanisms; components encountered in hydraulic servo controlled systems; systems oriented issues and much more.

In recent years there has been a revival of interest in the
hydraulic ram pump, a renewable energy water-lifting device.
"Hydraulic Ram Pumps" aims to introduce the reader to all aspects
of ram pumps. It should be useful to technicians and engineers
involved in rural water supply, whether they are assessing the
suitability of ram pumps, installing a system or contemplating
local manufacture. It gives practical guidelines for the
installation and operation of water supply systems based on such
pumps, as well as describing the operation of the pump and the
factors affecting its performance.;The reader is taken through the
steps involved in designing and installing a complete system, steps
that should be applicable to any model of ram pump available.
Details of one pump, designed for local manufacture in developing
countries, are given along with some notes on ram pump design for
those wishing to develop their own models.;A number of
illustrations are used alongside text in order to make the
information useful to a wide range of non-specialist readers.
Readers are welcome to photocopy the diagrams and add labels in
other languages in order for training purposes.

This volume collects various contributions from the 5th
International Conference on Jets, Wakes and Separated Flows
(ICJWSF2015) that took place in Stockholm during June 2015.
Researchers from all around the world presented their latest
results concerning fundamental and applied aspects of fluid
dynamics. With its general character, the conference embraced many
aspects of fluid dynamics, such as shear flows, multiphase flows
and vortex flows, for instance. The structure of the present book
reflects the variety of topics treated within the conference i.e.
Jets, Wakes, Separated flows, Vehicle aerodynamics, Wall-bounded
and confined flows, Noise, Turbomachinery flows, Multiphase and
reacting flows, Vortex dynamics, Energy-related flows and a section
dedicated to Numerical analyses.
This outstanding thesis characterises the aerodynamic flow around a
container freight train; investigating how changing container
loading configurations affect the magnitude of aerodynamic forces
measured on a container. 1/25th scale moving-model freight train
experiments were carried out at the University of Birmingham's
TRAIN rig facility to investigate slipstream velocities and static
pressure, as well as measuring, using a specifically designed
on-board pressure monitoring system, the aerodynamic loads on
containers. Results were compared with full scale data and assessed
in terms European standards for trackside worker and passenger
safety limits. Rail vehicle aerodynamic studies have tended to
previously focus on high speed passenger trains in line with
increases in train speed. The research presented within this thesis
highlights the issues associated with the aerodynamic development
around a freight train, providing the foundations for further
research and a basis from which to develop international safety
standards in relation to freight, as well as high speed trains.
This book presents a collection of papers from an IMechE event held
in February 2004. Materials are critical to the safety,
reliability, performance and total life cycle costs of machines,
and are therefore of great importance to both users and suppliers.
The papers in this volume review: the increasing availability and
improvements of superior materials over the last decade, moving
from niche markets to a wide field of applications; the advancement
of materials from the experimental stage to the point where they
can make real contributions to machine life and reliability; new
developing or nontraditional materials which have real potential
for future reduction in life cycle costs of fluid machinery.
"Advanced Materials for Fluid Machinery" will be of value to all
those involved in materials for fluid machinery, including
manufacturers and users, material suppliers, refurbishers,
contractors, consultants, materials specialists and researchers.
This volume constitutes the results of the International Conference
on Underwater Environment, MOQESM'14, held at "Le Quartz"
Conference Center in Brest, France, on October 14-15, 2014, within
the framework of the 9th Sea Tech Week, International Marine
Science and Technology Event. The objective of MOQESM'14 was to
bring together researchers from both academia and industry,
interested in marine robotics and hydrography with application to
the coastal environment mapping and underwater infrastructures
surveys. The common thread of the conference is the combination of
technical control, perception, and localization, typically used in
robotics, with the methods of mapping and bathymetry. The papers
presented in this book focus on two main topics. Firstly, coastal
and infrastructure mapping is addressed, focusing not only on
hydrographic systems, but also on positioning systems, bathymetry,
and remote sensing. The proposed methods rely on acoustic sensors
such as side scan sonars, multibeam echo sounders, phase-measuring
bathymetric sonars, as well as optical systems such as underwater
laser scanners. Accurate underwater positioning is also addressed
in the case of the use of a single acoustic beacon, and the latest
advances in increasing the vertical precision of Global Navigation
Satellite System (GNSS) are also presented. Most of the above
mentioned works are closely related to autonomous marine vehicles.
Consequently, the second part of the book describes some works
concerning the methods associated with such type of vehicles. The
selected papers focus on autonomous surface or underwater vehicles,
detailing new approaches for localization, modeling, control,
mapping, obstacle detection and avoidance, surfacing, and software
development. Some of these works imply acoustics sensing as well as
image processing. Set membership methods are also used in some
papers. The applications of the work presented in this book concern
in particular oceanography, monitoring of oil and gas
infrastructures, and military field.
This book presents flight mechanics of aircraft, spacecraft, and
rockets to technical and non-technical readers in simple terms and
based purely on physical principles. Adapting an accessible and
lucid writing style, the book retains the scientific authority and
conceptual substance of an engineering textbook without requiring a
background in physics or engineering mathematics. Professor Tewari
explains relevant physical principles of flight by straightforward
examples and meticulous diagrams and figures. Important aspects of
both atmospheric and space flight mechanics are covered, including
performance, stability and control, aeroelasticity, orbital
mechanics, and altitude control. The book describes airplanes,
gliders, rotary wing and flapping wing flight vehicles, rockets,
and spacecraft and visualizes the essential principles using
detailed illustration. It is an ideal resource for managers and
technicians in the aerospace industry without engineering degrees,
pilots, and anyone interested in the mechanics of flight.
This book presents contributions to the 19th biannual symposium of
the German Aerospace Aerodynamics Association (STAB) and the German
Society for Aeronautics and Astronautics (DGLR). The individual
chapters reflect ongoing research conducted by the STAB members in
the field of numerical and experimental fluid mechanics and
aerodynamics, mainly for (but not limited to) aerospace
applications, and cover both nationally and EC-funded projects.
Special emphasis is given to collaborative research projects
conducted by German scientists and engineers from universities,
research-establishments and industries. By addressing a number of
cutting-edge applications, together with the relevant physical and
mathematics fundamentals, the book provides readers with a
comprehensive overview of the current research work in the field.
Though the book's primary emphasis is on the aerospace context, it
also addresses further important applications, e.g. in ground
transportation and energy.
