Nanofluids in Heat Exchangers

This book contains five chapters describing nanofluids, their correlations for thermophysical properties, experimental setup, and testing of the performance of nanofluids of different nanoparticle concentrations and the base fluid in a real-world building heating air coil. The study is supplemented by computational fluid dynamics and heat transfer modeling in a microchannel heat exchanger to cool electronic equipment and computer chips. Chapters 2 and 4 present many recent correlations of viscosity, thermal conductivity, density, and specific heat that are necessary for design calculations. Chapter 4 shows through data the challenges encountered in practical applications when the dispersion stability of nanofluids cannot be maintained long-term, resulting in degraded performance. Future research in developing robust surfactants and dispersants is recommended. The book will benefit future nanofluids researchers contemplating experimental and computational work.
