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. This book serves as a sourcebook for those individuals involved in the design processes of microchannel flow passages in a heat exchanger. Each chapter is accompanied by a 'real life' case study. New edition of the first book published solely dealing with heat and fluid flow in minichannels and microchannels. Presents 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.
