Pressestimmen

From the reviews:

"This monograph discuss many aspects of flow and heat transfer in single channels and networks of channels. ... this book is a valuable contribution to the literature on heat transfer and single and two-phase flow in small channels. The book is nicely put together and largely free of typographical errors. ... All readers will gain something from spending time with this book. In addition, the authors have succeeded in producing a monograph that should motivate new research in the field." (Howard A. Stone, International Journal of Multiphase Flow, Vol. 35 (6), 2009)

"The topic of micro-channels finds a very large range of applications, particularly in the context of cooling of electronic equipment, and this book is of particular importance to the field. ... The book fills a gap in the existing literature and covers a large body of new knowledge in the thermo-fluid dynamics and applications in micro-geometries. ... Intended for both academic and industrial audiences ... . The book is recommended for libraries, R & D establishments as well as for educational institutions." (K. N. Shukla, Zentralblatt MATH, Vol. 1156, 2009)
