The third edition is divided into five parts. Part one describes some important basic concepts. Part two describes unit operations that take place at ambient temperature or involve minimum heating of foods. Part three includes operations that heat foods to preserve them or to alter their eating quality. Part four describes operations that remove heat from foods to extend their shelf life with minimal changes in nutritional quality or sensory characteristics. Part five describes post-processing operations, including packaging and distribution logistics. ...
During the past 20 years, design and operation of the comfort systems for buildings have been transformed
because of energy conservation imperatives, the use of computer-based design aids, and major advances
in intelligent management systems for buildings. In the 1970s, rules of thumb were widely used by
designers. Today, a strong analytical basis for the design synthesis process is standard procedure. This
handbook describes the latest methods for design and operation of new and existing buildings.
Heat treatment and surface engineering are seen as crucial elements in the design and manufacture of strategic components in a wide range of market sectors and industries including air, sea and land transportation, energy production, mining, defense or agriculture. This book offers a broad review of recent global developments in an application of thermal and thermochemical processing to modify the microstructure and properties of a wide range of engineering materials.
A heat exchanger is a vessel that transfers heat energy from one process stream to another. A common physical configuration for heat exchangers is a shell and tube exchanger, where a bundle of tubes sits inside a shell. There is no mixing of fluid between the shell and the tubes.
Microwave heating has found many applications ranging from the microwave ovens in kitchen to heat food, to a sterilization apparatus for medical treatment, to materials processing in the various fields. In those applications, microwave heating demonstrates significant advantages over conventional methods in reduced processing time and less environmental impacts. This book is comprised of eight chapters within three parts highlighting different aspects covering both the basic understandings and the advanced applications....
This book is intended as a guide to the selection or design of the principal kinds of chemical process equipment by engineers in school and industry. The level of treatment assumes an elementary knowledge of unit operations and transport phenomena.
As motive force of processes, heat must be transferred from one fluid to other, task
that is performed by means of heat exchangers. From this point of view, heat
exchangers represent an important element of thermal facilities that has substantially
contributed to technical development of the society. Today it is impossible to imagine
any branch of process engineering and energy technology without involvement of heat
exchangers. Advanced models of these apparatus were proposed in the middle of the
18th century, while theoretical backgrounds have been completed a century later....
Heat transfer is a fundamental part of thermal engineering. It is the science of the rules
governing the transfer of heat between systems of different temperatures. In thermodynamics,
the heat transferred from one system to its surroundings is assumed as a
given process parameter. This assumption does not give any information on how the
heat is transferred and which rules determine the quantity of the transferred heat.
Heat transfer describes the dependencies of the heat transfer rate from a corresponding
temperature difference and other physical conditions....
AIR-HEATING PROCESSES Air can be heated by burning fuel or by recovering waste heat from another process. In either case, the heat can be transferred to air directly or indirectly. Indirect air heaters are heat exchangers wherein the products of combustion never contact or mix with the air to be heated. In waste heat recovery, the heat exchanger is termed a recuperator. Direct air heaters or direct-fired air heaters heat the air by intentionally mixing the products or combustion of waste gas with the air to be heated. ...
Energy is defined as the capacity of a substance to do work. It is a property of the substance and
it can be transferred by interaction of a system and its surroundings. The student would have
encountered these interactions during the study of Thermodynamics. However, Thermodynamics
deals with the end states of the processes and provides no information on the physical
mechanisms that caused the process to take place. Heat Transfer is an example of such a process.
A convenient definition of heat transfer is energy in transition due to temperature differences.
The definition for dielectric constant relates to the permittivity of the material (symbol use
here ε). The permittivity expresses the ability of a material to polarise in response to an
applied field. It is the ratio of the permittivity of the dielectric to the permittivity of a
vacuum. Physically it means the greater the polarisation developed by a material in an
applied field of given strength, the greater the dielectric constant will be. Traditionally
dielectric materials are made from inorganic substances eg. mica and silicon dioxide.
A heat and mass transfer were two processes which occurred during vacuum frying potato chips. The heat transfer process included the convection of heat from the surface to the product and the conduction of heat into the product.
A mathemalical model is presented that describes heat and moisture transfer during the holpressing of MDF. The model includes conduction of heat between the press platens and the central layer of the mattress, phase change of water from the adsorbed to the vapor state and the convective heat and mass transfer through the edges of the mattress. This approach results in a three-dimensional unsleady-state problem in which the properties of the wood fibers, water and the wood-water system are dependent on temperature, mattress moisture content and steam pressure.
When we thus contemplate the process of social hygiene, we are no longer in danger of looking upon it as an
artificial interference with Nature. It is in the Book of Nature, as Campanella put it, that the laws of life and of
government are to be read. Or, as Quesnel said two centuries ago, more precisely for our present purpose,
"Nature is universal hygiene." All animals are scrupulous in hygiene; the elaboration of hygiene moves pari
passu with the rank of a species in intelligence. Even the cockroach, which lives on what we call filth, spends
the greater part of its time in the...
This is the third edition of a physical chemistry textbook designed for a two-semester
undergraduate physical chemistry course. The physical chemistry course is often the
ﬁrst opportunity that a student has to synthesize descriptive, theoretical, and mathe-
matical knowledge about chemistry into a coherent whole. To facilitate this synthe-
sis, the book is constructed about the idea of deﬁning a system, studying the states
in which it might be found, and analyzing the processes by which it can change
Ours is a very young profession: when the first edition of the
Instrument Engineers’ Handbook (IEH) came out, Marks’
Mechanical Engineers’ Handbook was in its fifth edition, and
Perry’s Chemical Engineers’ Handbook was in its sixth!
Now, as we are starting to work on the fourth edition of the
IEH, we are already in a new millenium. But while our
profession is young, we are also unique and special.
Electrical machines are almost entirely used in producing electricity, and there are very few
electricity-producing processes where rotating machines are not used. In such processes,
at least auxiliary motors are usually needed. In distributed energy systems, new machine
types play a considerable role: for instance, the era of permanent magnet machines has now
About half of all electricity produced globally is used in electric motors, and the share of
accurately controlled motor drives applications is increasing.
Enormous number of books, reviews and original papers concerning engineering
applications of heat transfer has already been published and numerous new
publications appear every year due to exceptionally wide list of objects and processes
that require to be considered with a view to thermal energy redistribution. All the
three mechanisms of heat transfer (conduction, convection and radiation) contribute to
energy redistribution, however frequently the dominant mechanism can be singled
