ABSTRAKT
This year, three people who have made significant contributions to the field of enhanced heat transfer have retired after a distinguished careers in the field. We would like to recognize their contributions and wish them well in the future.
Prof. Wataru Nakayama retired from his position at Tokyo University in the Spring. Working at the Hitachi Mechanical Engineering Research Lab, Prof. Nakayama and his co-workers performed pioneering experimental and theoretical work on enhanced boiling surfaces. Their work proposed a boiling mechanism, and they developed the first rationally based analytical model of boiling on a "structured" enhanced surface. Other important contributions at Hitachi include the "micro-fin" tube, which is now used in nearly all refrigeration evaporators and condensers, and the convex-louver air-side fin geometry. During his tenure at Tokyo Institute, Prof. Nakayama focused on cooling of electronic equipment. Upon his retirement there, Dr. Nakayama moved on to a research appointment in the U.S., where he continues his work on cooling of electronic equipment at the University of Maryland. Dr. Nakayama is one of the first pioneers in working to developing and explaining how enhanced surfaces work. Prof. Nakayama was also the first Regional Editor for the Journal of Enhanced Heat Transfer in Japan.
Prof. Arthur Bergles is now on a terminal sabbatical leave from his position at Rensselaer Polytechnic University. He is perhaps best known for his diligent work to publicize the field of enhanced heat transfer through his handbook chapters, his Bibliography of Augmentation on Enhanced Heat and Mass Transfer, and his many international lectures. Prof. Bergles and his co-workers maintained and updated the Bibliography over nearly 20 years. He has also published major review articles on the subject of enhanced heat transfer in various handbooks. Prof. Bergles developed a fascination with the "twisted-tape" insert for flow in tubes. He published a series of papers on this topic, culminating in his 1993 papers that provides a rationally based correlation to predict its performance in laminar and turbulent flow. Prof. Bergles has also published many papers that report the performance of enhanced surfaces, and he used "performance evaluation criteria" to evaluate the performance benefits of the enhanced surfaces he tested. His work spans virtually all aspects in enhanced heat transfer. Prof. Bergles serves as Advisory Editor for the Journal of Enhanced Heat Transfer.
Prof. Paul Marto retired this Spring from his position at the Naval Postgraduate School in Monterey, CA. Paul focused primarily on boiling and condensation of enhanced surfaces in his research career. He has investigated many geometry variants of enhanced boiling and condensing surfaces, including a series of papers that report the effect of fin height and spacing for condensation on horizontal, integral-fin tubes. Paul has served as the organizer of many conferences on heat transfer, and was invited to write a paper on "condensation" for the special 50th year issue of the Journal of Heat Transfer (1988). He has also been author of several handbook chapters on condensation. Prof. Marto continues as a Regional Editor of the Journal of Enhanced Heat Transfer.
