Interest in fuel cells and thermally activated (heat pipe heat exchangers) adsorption systems using natural refrigerants and/or alternatives to HFC-based refrigerants has increased significantly. During the last few decades, research aimed at the development of thermally powered adsorption cooling technologies has also intensified. This book covers state-of-the-art adsorption research and technologies for relevant applications based on the use of efficient heat-transfer devices-heat pipes and two-phase thermosyphons-with the objectives of energy efficiency and sustainability. It explores a range of topics, including the heat pipe thermal control of spacecraft.

Leonard L. Vasiliev is president of the NIS Association "Heat Pipes" and head of the Porous Media Laboratory, A.V. Luikov Heat and Mass Transfer Institute, National Academy of Sciences, Belarus. He obtained his first doctorate degree (Candidate of science) in 1964 in Minsk. He is currently a member of the Scientific Council of the International Centre for Heat and Mass Transfer. Professor Vasiliev has authored or co-authored about 340 publications in journals and conference proceedings. He is the author and co-author of 14 books, 218 Soviet authors' certificates on invention, and 12 patents.

Sadik Kakac received his degree of Dip.-Ing (1955) from the Department of Mechanical Engineering at the Technical University of Istanbul (ITU, MS degrees from MIT in mechanical (1959) and nuclear engineering (1960). He has authored or co-authored over 200 scientific papers on transient and steady-state laminar, turbulent forced convection, two-phase flow instabilities, fuel-cells modeling, micro heat transfer with sleep flow, and Micro/nano heat transfer. He is a fellow member of ASME and a recipient of the ASME heat transfer memorial award. He is a member of the scientific council and executive committee. Prof. Kakac edited and co-edited 14 volumes on thermal and fluid sciences and applications including a hand book o convective heat transfer.
