Book Description
Phase-change Material based heat sinks and associated optimization remains a topic of great interest, as evident from the increasing number of citations and new applications and miniaturization. Often the multi objective perspective of such heat sinks is ignored. This book introduces the readers to the PCM based heat sinks and Multi objective optimization. The authors have also included interesting in house experimental results on the "Rotating heat sinks" which is a first of a kind work. Useful to budding thermal researchers and practicing engineers in the field, this book is also a great start for students to understand the cooling applications in electronics and an asset to every library in a technical university. Since this book not only gives a critical review of the state of the art but also presents the authors' own results. The book will encourage, motivate and let the reader consider pursuing a research career in electronic cooling technologies.

Book Description
Development of next generation microchips and other high heat generating applications is constrained by the issue of effective heat removal. One of the most promising methods to enhance heat transfer is to introduce nano-sized phase change material (PCM) particles in the heat transfer fluid. In this work, commercial Computational Fluid Dynamics (CFD) software ANSYS Fluent was employed for modeling the thermal performance of liquid flow with nanosized PCM particles in a microchannel. The research carried out here resulted in a thorough quantitative assessment of heat storage capacity enhancement which can be achieved through the use of nanosized phase change material particles. The results showed tremendous potential for using nanosized phase change materials in liquid heat sinks for effective heat removal in high heat generating applications.

Book Description
Nanofluids, i.e., dilute suspensions of nanoparticles in liquids, may exhibit quite different thermal properties than the pure carrier fluids. For example, numerous experiments with nanofluids have shown that the effective thermal conductivities for such mixtures are measurably elevated, and hence beneficial applications to (micro-scale) cooling are obvious. A very different application of nanofluids could be in modern medicine, where for example, nanodrugs are mixed in microchannels for controlled delivery with bio-MEMS. In general, to optimize nanofluid flow in microchannels, best possible conduit geometries, mixing units, and device operational conditions have to be found for specific applications. Specifically, a suitable model of common nanofluids, performance as well as cost effective mixers, and entropy minimizing channel designs are the prerequisites for achieving these project objectives. Two effective thermal conductivity models for nanofluids were compared in detail, where the new KKL (Koo-Kleinstreuer-Li) model, based on Brownian-motion induced micro-mixing, achieved good agreements with the currently available experimental data sets. The thermal performance of nanofluid flow in a trapezoidal microchannel was analyzed using pure water as well as a nanofluid, i.e., CuO-water, with volume fractions of 1% and 4% CuO-particles with . It was found that nanofluids do measurably enhance the thermal performance of microchannel mixture flow with a small increase in pumping power. Specifically, the thermal performance increases with volume fraction; but, the extra pressure drop, or pumping power, will somewhat decrease the beneficial effects. Microchannel heat sinks with nanofluids are expected to be good candidates for the next generation of cooling devices. Microcooling device design aspects in light of minimization of entropy generation were investigated numerically. The influence of the Reynolds number (inlet velocity), fluid inlet temperature, channel geometr.

Book Description
Nanofluids are solid-liquid composite material consisting of solid nanoparticles suspended in liquid with enhanced thermal properties. This book introduces basic fluid mechanics, conduction and convection in fluids, along with nanomaterials for nanofluids, property characterization, and outline applications of nanofluids in solar technology, machining and other special applications. Recent experiments on nanofluids have indicated significant increase in thermal conductivity compared with liquids without nanoparticles or larger particles, strong temperature dependence of thermal conductivity, and significant increase in critical heat flux in boiling heat transfer, all of which are covered in the book.
