THE 2022
NUKIYAMA MEMORIAL AWARD
Presented toJUNICHIRO SHIOMI
at the 59th National Heat Transfer Symposium of JapanMay 19, 2022
by the Heat Transfer Society of Japan

The great merit of integrating the broad subfields can be seen in Dr. Shiomi’s achievement inestablishing the phonon engineering platform, where he realized development of thermalfunctional solid materials based on material design guidelines obtained by coupling the four
approaches: theoretical and numerical analysis, physical property measurement, structure
fabrication, and machine learning. Having pioneered materials informatics for heat transfer, hehas innovated the ways to design structures and materials that control heat transport by meansof nanostructures and interfacial structures and has succeeded in developing materials withhigh-performance thermoelectric conversion, heat dissipation, thermal insulation, and thermalradiation.
Dr. Shiomi has delivered more than 30 invited or keynote lectures at international conferences
and has won 12 awards from various organizations including Zeldovich Medal from theCommittee on Space Research, the Young Scientists’ Prize, The Commendation for Science andTechnology by the Minister of Educational, Culture, Sports, Science and Technology, Academicaward of Heat Transfer Society of Japan, Academic award of Thermoelectrics Society of Japan,and JSPS Prize.

Junichiro Shiomi
Dr. Junichiro Shiomi was born in Okayama, Japan in 1975. He obtained his BE degree in 1999
from Tohoku University, Japan, and Ph. D. degree in 2004 from Royal Institute of Technology(KTH), Sweden. After being a JSPS postdoctoral fellow, he has been a faculty at Department ofMechanical Engineering, the University of Tokyo, as Research Associate (2007-2008), Lecturer(2008-2010), Associate Professor (2010-2017), and Professor (2017-present). Since 2019, he hasbeen Head/Chair of Department of Mechanical Engineering. Since 2010 he has founded and led
Thermal Energy Engineering Lab, pursuing research to advance thermal management, waste
heat recovery, and energy harvesting technologies based on nano-to-macro innovation inmaterials, structures, and systems.
Dr. Shiomi has served in several committees in Heat Transfer Society of Japan includingSpecific Promotion Research Committee, where he led Specific Promotion Research in
Nanoscale Heat Transfer. He is a Fellow of Japan Society of Mechanical Engineers, Director in
Thermoelectrics Society of Japan, and Member of the Science Council of Japan. He was also
Associate Editors of Transactions of Japan Society of Mechanical Engineers, Applied Physics
Express, and Japanese Journal of Applied Physics. He has been Organizing Member, Advisory,and Executive Committee of many international conferences.
He is a world-leading scholar in the field of nanoscale heat transfer, with the outstanding
contribution to the field by developing unique methodologies and discovering new principles
and controllability. He has been active in a wide range of sub-fields such as thermal energy
management from fundamentals of heat conduction, phase change, and thermoelectric
conversion to the system level, interfacial fluid dynamics and electro-kinetics, multiscale andmultiphysics computation of transport phenomena, controlled synthesis and device integrationof nanomaterials, thermal property measurements at the nanoscale, and materials informatics.
He has published over 200 refereed journal papers with total citation and h-index of over 5,000
and 40 (by Scopus).

The Nukiyama Memorial Award
The Nukiyama Memorial Award has been established in 2011 by the Heat Transfer Society ofJapan to commemorate outstanding contributions by Shiro Nukiyama as an excellent heat transferscientist. Nukiyama addressed the challenges of the boiling phenomena and published apioneering paper which clarified these phenomena in the form of the Nukiyama curve (boilingcurve). This epoch-making work was done in 1930s, when heat transfer research was in an earlystage and Nukiyama himself was young, under forty years old. The Nukiyama Memorial Award
shall be bestowed to a scientist under/ about fifty years of age, once every two years in the fieldof Thermal Science and Engineering.

Shiro Nukiyama was born in 1896 in Tokyo, Japan. He graduated from Tokyo Imperial University, andimmediately started his professional career as a Lecturer of Tohoku Imperial University (currently Tohoku
University). He was appointed Associate Professor in 1921. He visited England, Germany, Switzerland
and the United States in 1922~24. He was appointed Professor in 1926. In subsequent years he activelyconducted boiling heat transfer research.
In 1934, Nukiyama published a pioneering paper*) which was entitled “The Maximum and Minimum
Values of the Heat Q Transmitted from Metal to Boiling Water under Atmospheric Pressure.” This paper
clarified and provided an overview of the boiling phenomena in the form of the Nukiyama Curve (boilingcurve).
In this work, Nukiyama made an excellent experiment using a metallic wire or a metal wire), in which
temperature and heat flux are evaluated accurately, and found that the relation between degree ofsuperheating and heat flux is not monotonous, and that a maximum heat flux points appears in the nucleateboiling region and a minimum heat flux point appears in the film boiling region. He also found thehysteresis behavior that occurs in the transition region between the nucleate boiling and film boiling.
Furthermore, he suggested that the boiling curve can be drawn even in the transition region if the state of
the boiling water can be changed quasi-statically.
This was an epoch-making work which clarified the physics of boiling phenomena first. It has been highly
appreciated in the international academic world of heat transfer. Also, it has become a guideline to heattransfer engineering for the design and control of combustion boilers and/or steam generators, and as such it
has laid the foundation of modern energy technology. The Nukiyama Curve appears in every textbook of heattransfer today. Nukiyama is a great person in the international academic world of heat transfer.
In 1956 Nukiyama retired from Tohoku University, and was granted the title of Professor Emeritus. He
served as the President of the Heat Transfer Society of Japan in 1963~64. He received the Max Jacob
Memorial Award in 1968. In 1983, he passed away in Sendai, Japan.
