  • Fluid mechanics is a fundamental branch of civil, chemical, and mechanical engineering which deals with the behavior of liquids and gases, particularly while flowing. This chapter provides a brief review of the vocabulary and fundamental equations of fluid mechanics, and reminds the HVAC designer of the scientific principles underlying much of the day-to-day applied science calculations. See Ref. 1 or a fluid mechanics text for additional detail.

  • Since the First International Congress on Liquid Crystals (Lcs), held at Kent State University, OH, USA, in 1965, the implications of these systems associated with various aspects of telecommunications, laser, display, automobile, aerospace technologies, thermo-optics, medicine and biology have been the subject of considerable debate among researchers, scientists and engineers. Indeed, LCs, being a unique mesomorphic phase of matter, combine properties of both solids (long-range orientation order, manifestations of Bragg diffraction, etc.) and liquids (fluidity, viscosity, etc.).

  • I am enormously grateful to all of authors who have contributed to this volume on gas– liquid foam. One of the great pleasures of working with such accomplished scientists and engineers from industry and academia is that everybody has known the level at which to pitch their contributions. Special thanks are due to Laurie Schramm who, along with co-authors, has contributed two chapters on foams in enhanced oil recovery and flotation of oil sands, and to Thomas Martin who endured initial confusion upon my part to produce a first class chapter on firefighting foams....

  • When analyzing kinetic data or designing a chemical reactor, it is important to state clearly the definitions of reaction rate, conversion, yield, and selectivity. For a homogeneous reaction, the reaction rate is defined either as the amount of product formed or the amount of reactant consumed per unit volume of the gas or liquid phase per unit time. We generally use moles (g mol, kg mol, or lb mol) rather than mass to define the rate, since this simplifies the material balance calculations.

  • The aim of this book is to provide a practical engineering description of techniques and processes in widespread use and, where feasible, provide sufficient design and operating data to permit evaluation of the processes for specific applications. Limited data on processes that were once, but are no longer commercially important, are also presented to pvide an histor - ical perspective. Subject matter is generally limited to the removal from gas streams of gas - phase impurities that are present in relatively minor proportions.

  • Thermodynamics is one of the most exciting branches of physical chemistry which has greatly contributed to the modern science. Since its inception, great minds have built their theories of thermodynamics. One should name those of Sadi Carnot, Clapeyron Claussius, Maxwell, Boltzman, Bernoulli, Leibniz etc. Josiah Willard Gibbs had perhaps the greatest scientific influence on the development of thermodynamics. His attention was for some time focused on the study of the Watt steam engine.

  • Pulsed lasers are available in the gas, liquid, and the solid state. These lasers are also enormously versatile in their output characteristics yielding emission from very large energy pulses to very high peak-power pulses. Pulsed lasers are equally versatile in their spectral characteristics.

  • Organic light-emitting diodes (OLED) are playing a major role in information technology (IT) by providing the promise of further expanding the use of digital displays through making display fabrication technology lower in cost and higher in performance to replace liquid crystal displays (LCD). Due to various attractive features such as high contrast, high brightness, large color gamut and thin structure, various sized OLED displays from small-sized mobile phone display to large-sized TV display have already begun to be mass-produced....

  • An integrated gasification process was developed for an Ohio-based kraft pulp mill to produce liquid transportation fuels from biomass and coal. Black liquor byproduct from the pulp mill is co-gasified with coal to generate high quality syngas for further synthesis to dimethyl ether (DME) and/or Fischer-Tropsch fuels. A Texaco gasifier was chosen as the focal point for this design. Whenever possible, energy is recovered throughout to generate heat, steam, and power. Mass and energy balances were performed for individual process components and the entire design.

  • Mass transfer is often the rate limiting step in gas-liquid reactions, and novel reactor designs that increase mass transfer can reduce reactor size and also improve process yields. As an example (Koestler 1992), an organic material was originally chlorinated in a glass-lined batch stirred tank reactor, with chlorine fed through a dip pipe.

  • Nucleate pool boiling is a daily phenomenon transferring effectively high heat flux. It is, however, a very complex and illusive process because of the interrelation of numerous factors and effects as the nucleate process, the growth of the bubbles, the interaction between the heater’s surface with liquid and vapor, the evaporation process at the liquidvapor interface, and the transport process of vapour and hot liquid away from the heater’s surface.

  • Friction Drives with Clutch Capability Friction drives that also have clutch capabilities are attractive because they are relatively simple and inexpensive. However, they have been inherently limited to relatively low-power applications because of their dependence upon a coefficient of friction that is usually less than 0.6 between the contacting materials. A friction drive was used in an early automobile, but it was discontinued because of its power limitation.

  • This book on internal combustion engines brings out few chapters on the research activities through the wide range of current engine issues. The first section groups combustion-related papers including all research areas from fuel delivery to exhaust emission phenomena. The second one deals with various problems on engine design, modeling, manufacturing, control and testing. Such structure should improve legibility of the book and helps to integrate all singular chapters as a logical whole.

  • Supplementing aids can be paid for liquid skimmed milk used in the manufacture of casein and in feeding. They can also be approved for SMP employed in feedstuff, making it more competitive compared to vegetable proteins. The subsidy rate granted takes into account market conditions, e.g. it was reduced to zero in October 2006, as EU market prices for milk protein became exceptionally high. In general, comparable aids are provided for the use of cream, butter and concentrated butter.
