Thermal power plants are one of the most important process industries for engineering professionals. Over the past decades, the power sector is facing a number of critical issues; however, the most fundamental challenge is meeting the growing power demand in sustainable and efficient ways. Practicing power plant engineers not only look after operation and maintenance of the plant, but, also look after range of activities including research and development, starting from power generation to environmental aspects of power plants.

At the beginning of the 19th century the description of matter attained, what one
would call today, a scientific basis. Dalton1 supported the atomic theory with
experiments permitting the development of modern chemistry. The book “A New
System of Chemical Philosophy,” describes this new approach. In Fig. 1.1, an
excerpt is displayed. Chapters I and II give a summary of the contemporary
understanding of nature by analyzing heat and mass, the two basic building-blocks
of any material. Chapter I displays the theory of the caloric as it was generally...
Heat transfer has emerged as a central discipline in contemporary engineering science.
The research activity of a few decades ago—the material reviewed in the first
handbooks—has distilled itself into textbook concepts and results. Heat transfer has
become not only a self-standing discipline in the current literature and engineering
curricula, but also an indispensable discipline at the interface with other pivotal and
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.
This book includes contributions from researchers around the world on numerical developments and applications to predict fluid flow and heat transfer, with an emphasis on thermal hydraulics computational fluid dynamics. Our ability to simulate larger problems with greater fidelity has vastly expanded over the past decade. The collection of material presented in this book augments the ever-increasing body of knowledge concerning the important topic of thermal hydraulics.
An important aspect of nuclear reactor core analysis involves the determination of the optimal coolant flow distribution and pressure drop across the reactor core. On the one hand, higher coolant flow rates will lead to better heat transfer coefficients and higher Critical Heat Flux (CHF) limits. On the other hand, higher flows rates will also in large pressure drops across the reactor core, hence larger required pumping powers and larger dynamic loads on the core components.
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....
The utilisation of renewable energies is not at all new; in the history of mankind
renewable energies have for a long time been the primary possibility of generating
energy. This only changed with industrial revolution when lignite and hard coal
became increasingly more important. Later on, also crude oil gained importance.
Offering the advantages of easy transportation and processing also as a raw
material, crude oil has become one of the prime energy carriers applied today.
Heating ventilating and air conditioning is the technology of indoor and vehicular environmental comfort. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. Refrigeration is sometimes added to the field's abbreviation as HVAC&R or HVACR, or ventilating is dropped as in HACR (such as the designation of HACR-rated circuit breakers).
The radiation of the sun in which the planet is incessantly plunged, penetrates
the air, the earth, and the waters; its elements are divided, change
direction in every way, and, penetrating the mass of the globe, would raise
its temperature more and more, if the heat acquired were not exactly
balanced by that which escapes in rays from all points of the surface and
expands through the sky.
Thermal Analysis is a well-established set of techniques for obtaining qualitative and quantitative information about the effects of various heat treatments on materials of all kinds, including new chemical compounds, plastics, ceramics, alloys, construction materials, minerals, foods and medicines. Heating is performed under strictly controlled conditions and can reveal changes in structure and other important properties of the material being studied. Such studies are of great practical importance in the use of materials....
Effect of wollastonite nanofibers on the improvement of thermal conductivity coefficient of Medium-Density Fiberboard (MDF) was studied here to find a possible solution to decrease hot-press time as a bottle-neck during composite production. Nanowollastonite was applied at 10%, based on the dry weight of wood fibers. Density of the control MDF boards was 0.66 g/cm3. Thermal conductivity coefficient was measured using an apparatus based on Fourier’s Law for heat conduction.

A steady state thermal analysis calculates effects of constant thermal loads on a model and is used to determine temperatures, heat flow rates, and the heat fluxes in a part. A steady state analysis is commonly used as a precursor to a transient thermal analysis to determine the initial conditions.
The present science book "Application of Solar Energy" is edited by Professor R. D. Rugescu in the series on Solar Power and consists of 7 chapters that begin with the proof of the high thermal efficiency of the gravitational draught through concentrated solar heating. It continues with novel technologies of producing organic fuels through solar heating, new types of photovoltaic cells, long term use of thermal solar power plants, the efficiency of thermal storage and applications in Niger of the Solar power.
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
