Book Description
Heat exchangers with minichannel and microchannel flow passages are becoming increasingly popular because of their ability to remove large heat fluxes under single-phase and two-phase applications. Heat Transfer and Fluid Flow in Minichannels and Microchannels serves as a sourcebook for those individuals involved in the design processes of microchannel flow passages in a heat exchanger. This book manages to present its findings in a manner that is directly useful to a designer, while a researcher is able to use the information in developing new models, or in identifying research needs Each chapter is accompanied by a ‘real life' case study First book published solely dealing with heat and fluid flow in minichannels and microchannels

Book Description
The subject of the book is uid dynamics and heat transfer in micro-channels. This problem is important for understanding the complex phenomena associated with single- and two-phase ows in heated micro-channels. The challenge posed by high heat uxes in electronic chips makes thermal management a key factor in the development of these systems. Cooling of mic- electronic components by new cooling technologies, as well as improvement of the existing ones, is becoming a necessity as the power dissipation levels of integrated circuits increases and their sizes decrease. Miniature heat sinks with liquid ows in silicon wafers could signi cantly improve the performance and reliability of se- conductor devices. The improvements are made by increasing the effective thermal conductivity, by reducing the temperature gradient across the wafer, by reducing the maximum wafer temperature, and also by reducing the number and intensity of localized hot spots. A possible way to enhance heat transfer in systems with high power density is to change the phase in the micro-channels embedded in the device. This has motivated a number of theoretical and experimental investigations covering various aspects of heat transfer in micro-channel heat sinks with phase change. The ow and heat transfer in heated micro-channels are accompanied by a n- ber of thermohydrodynamic processes, such as liquid heating and vaporization, bo- ing, formation of two-phase mixtures with a very complicated inner structure, etc., which affect signi cantly the hydrodynamic and thermal characteristics of the co- ing systems.

Book Description
"Deviations in heat transfer predictions by classical theory for single-phase laminar flow in microchannels have been mainly attributed to surface roughness, deviations in channel dimensions, errors in measurement, entrance and exit effects. Identifying correct thermal boundary conditions in a given application also plays an important role in accurate estimation of heat transfer coefficients. Different thermal boundary conditions generally applied in fluid domain are: T, H1, and H2. However, there are very few solutions available for the heat transfer under the H2 boundary condition which is the most applicable thermal boundary condition in many microchannel heat exchangers. The current work aimed at addressing two outstanding issues in this field: (i) predicting heat transfer rate in rectangular channels under H2 boundary conditions, and (ii) numerically studying the effects of structured roughness on pressure drop and heat transfer. A numerical model is developed to predict accurate fluid flow and heat transfer effects in microchannels under H2 boundary condition. Numerical data sets are generated for rectangular microchannels with different heated wall configurations. Although the results are seen as relevant in microscale applications, they are applicable to any sized channels. Based on the numerical results obtained for a wide range of aspect ratios, generalized correlations for fully developed laminar Nusselt number as a function of channel aspect ratio are presented for all the cases. This information can provide better understanding and insight into the transport processes in the microchannels. Surface roughness effects in conventional ducts are minimal whereas for the micro-sized channel, the roughness effects needs to be taken into account for laminar flow. Developing a better insight of the fundamental effects of surface roughness in parallel plate microchannels is therefore essential. Based on various roughness characterization schemes, the effect of structured roughness elements for incompressible laminar fluid flow is analyzed and the proposed numerical model is extended to accurately predict the pressure drop and heat transfer coefficient in presence of roughness using CFD software, FLUENT. The results are compared with the available experimental data for some of the rough surfaces."--Abstract.

Book Description
In spite of its universality, mixing is poorly understood and generally speaking, mixing problems are attacked on a case-by-case basis. This is the first book to present a unified treatment of the mixing of fluids from a kinematical viewpoint. The author's aim is to provide a conceptually clear basis from which to launch analysis and to facilitate an understanding of the numerous mixing problems encountered in nature and technology. After presenting the necessary background in kinematics and fluid dynamics, Professor Ottino considers various examples of dealing with necessary background in dynamical systems and chaos. The book assumes little previous knowledge of fluid dynamics and dynamical systems and can be used as a textbook by final-year undergraduates, graduate students and researchers in applied mathematics, engineering science, geophysics and physics who have an interest in fluid dynamics, continuum mechanics and dynamical systems. It is profusely illustrated in colour, with many line diagrams and half-tones. Systems which illustrate the most important concepts, many exercises and examples are included.

Book Description
This first book in a new series in Thermal an Fluid Physics and Engineering, edited by Professor G.F. Hewitt, is of particular importance to the field at the present time. Edited by Professor F.P. Celata, the topic of microchannels is finding a very large range of applications, particularly in the context of cooling of electronic equipment. Fluid flow and heat transfer process at the microscale bring into play many aspects that are not significant at the macro scale. The book fills a void in the existing literature and covers a large body of new knowledge in the thermal-fluid dynamics theory and applications in micro-geometries. The volume also presents a critical assessment of the state-of-the-art in the field. Intended for both academic and industrial audiences.

Book Description
Laminar Flow Forced Convection in Ducts is a sourcebook for compact heat exchanger analytical data. This book describes the analytical solutions for laminar fluid flow and forced convection heat transfer in circular and noncircular pipes, including applicable differential equations and boundary conditions involving velocity and temperature problems of fluid flow. The book also discusses fluid flow—how much power is required to pump fluids through the heat exchanger, as well as the heat transfer—the determination of q" distribution, and the temperature of fluid and walls. The text also analyzes the coolant or heat transfer fluid flows in a nuclear power reactor composed of a bundle of circular section fuel rods located inside a round tube. R.A. Axford addresses fluid flow and heat transfers results for the rod bundle geometry in "Heat Transfer in Rod Bundles." The book also provides an overview and guidelines that can be used for the designer and the applied mathematician. This book is suitable for engineers working in electronics, aerospace, instrumentation, and biomechanics that use cooling or heating exchanges or solar collection systems.
