This book was released on 2011 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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.
Download or read book Fluid Flow Heat Transfer and Boiling in Micro Channels written by L. P. Yarin and published by Springer Science & Business Media. This book was released on 2008-09-19 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This book covers concepts and the latest developments on microscale flow and heat transfer phenomena involving a gas. The book is organised in two parts: the first part focuses on the fluid flow and heat transfer characteristics of gaseous slip flows. The second part presents modelling of such flows using higher-order continuum transport equations. The Navier-Stokes equations based solution is provided to various problems in the slip regime. Several interesting characteristics of slip flows along with useful empirical correlations are documented in the first part of the book. The examples bring out the failure of the conventional equations to adequately describe various phenomena at the microscale. Thereby the readers are introduced to higher order continuum transport (Burnett and Grad) equations, which can potentially overcome these limitations. A clear and easy to follow step by step derivation of the Burnett and Grad equations (superset of the Navier-Stokes equations) is provided in the second part of the book. Analytical solution of these equations, the latest developments in the field, along with scope for future work in this area are also brought out. Presents characteristics of flow in the slip and transition regimes for a clear understanding of microscale flow problems; Provides a derivation of Navier-Stokes equations from microscopic viewpoint; Features a clear and easy to follow step-by-step approach to derive Burnett and Grad equations; Describes a complete compilation of few known exact solutions of the Burnett and Grad equations, along with a discussion of the solution aided with plots; Introduces the variants of the Navier-Stokes, Burnett and Grad equations, including the recently proposed Onsager-Burnett and O13 moment equations.
