1. Major Societies
Most of Japanese scientists and engineers in thermal science and engineering (or more specifically heat andmass transfer) belong to the Heat Transfer Society of Japan (HTSJ), Thermal Engineering Division of the Japan
Society of Mechanical Engineers (JSME-TED), and Division of Thermal Engineering of the Society of Chemical
Engineering (SCEJ-DTE). The relationships among the three major societies are expressed as shown in Fig. 1.
Although the number of members of HTSJ are much less than that of JSME-TED, HTSJ is a core society of heatand mass transfer. This is because JSME-TED consists of a wide variety of thermal engineering applications.

3. Major Journals

8. Addendum
Japanese language belongs to Altaic languages; one of their typical features isa subject–object–verb (SOV) structure. After Chinese characters were transferred
to Japan in the 4th century, Hiragana and Katakana (Japanese characters) weredeveloped in the 8-9th century. As a result, we combinedly use the above threecharacters as shown in this example.

The pandemic took a heavy toll on the world, forcing us to change the way we work, learn, andinteract with others. It has been difficult time for the international academic community as well,as many of our scheduled events had to be cancelled or postponed. While there was disappointment
and confusion, especially in the initial phase of the pandemic, it was encouraging to see that the academic societies
immediately rose to the occasion and organized international conferences online, not only as an alternative to onsite but also to add values to the conferences with the help of digital transformation (DX). Such was the case with
the international heat transfer community. Some of the online conferences I attended might have been difficult toachieve prior to DX. One example was “International Colloquia on Thermal Innovations (InnoTherm)” series(http://meche.mit.edu/international-colloquia-thermal-innovations) organized by the colleagues at MIT (chairedby Prof. Gang Chen) aiming to stimulate and highlight innovations and advances in thermal energy conversion,storage, transport, and utilization. I had a pleasure to moderate a couple of sessions and was thrilled to see hundredsof participants from around the world vividly discussing across different disciplines.
Learning the usefulness of DX to discuss new interdisciplinary topics, Prof. Chris Dames (UC Berkeley), Prof.
Tengfei Luo (University of Notre Dame), Prof. Koji Tsuda (University of Tokyo), and I organized “NSF-JST Joint
Workshop on Thermal Transport, Materials Informatics and Quantum Computing” (https://aithermworkshop.nd.
edu) in March 2021. The workshop aimed to initiate conversations between the greater machine learning,materials informatics, quantum computing community and the thermal transport community to promoteinternational collaboration initiatives. Over the past few decades, research in thermal transport has led to significant
advancement in the understanding of fundamental physics and computational tools that can predict thermal
properties with high fidelity. However, applying such established knowledge and tools to design new materials forrelevant applications had been rather ad-hoc. With the recent prosperity of artificial intelligence (AI) and quantum
computing, there is an opportunity to leverage them to further advance thermal transport fundamental science andmaximize the ability to systematically develop thermal materials and processes with desirable performance. With
this in mind, we invited speakers on four topics: data infrastructure; simulation-aided materials informatics andthermal transport; AI-driven experiments; and quantum computing. The dialogue between researchers within andbetween each topic was very productive. Constructive discussions were also held with other stakeholders such as
governments and funding agencies. The workshop output several important action plans, including acomputational round-robin study, thermal transport property database, and international autonomous
experimentation, which initiated the on-going world-wide collaborations including researchers from Europe andChina. Such a simultaneous multi-stakeholder dialogue would have been difficult without the DX.
Of course, online events have their drawbacks. Time zones have been a major issue, especially for international
conferences. Many of us have given or heard a talk in the middle of the night fighting sleepiness. Recently, there
have been hybrid conferences, where the on-site and online events are held on different days, but in such cases,
the online portion is usually rather empty. Now that, in many places, the on-site events are restarting, we are rerecognizing how precious it is to meet and discuss in person. In fact, we had so much fun in the recent National
Heat Transfer Symposium of Japan held on-site (reported on the next page)!
While I very much look forward to the resumption of international heat transfer conferences on-site, an
important question may be “Are we going back to where we were before the pandemic?” or “Are there ways toimprove on-site international conferences utilizing DX?” The world is now facing a sustainability crisis and there
are growing expectations for academia to help solve it. Not to mention, the potential contribution from the field ofheat transfer is significant, and the issues need to be tackled internationally. Such social demands have been always
there, but the urgency is more than ever with critical timelines, which calls for efficient international collaboration
rather than competition. That requires more in-depth discussion in the international conferences, but how do we

do it? One idea is a “flip conference”. Like the “flip class”, DX schemes could be used to provide participants withdigital contents of presentation in advance so that they can spend more time for discussion on site. This can help
the participants understand better each other’s work and facilitate actual collaboration. Perhaps now is a goodtiming to think about transforming international conferences?
2. Report on 59th national heat transfer symposium of Japan (NHTSJ 2022)

NHTSJ 2022 (https://htsj-conf.org/symp2022/index_e.html) took place in face-toface and on-line virtual ways during May 18 to 20, 2022 in Gifu (Tokai district).
Totally 338 papers were presented including 9 keynotes through 30 sessions in the symposium. The share of
number of the presentation in each session is seen in Fig. 2.1. The Best Presentation Award Session is a poster
session presented by young researchers and students, and 6 candidates were awarded. The awarded researches
were 1) 3D analysis of heat transfer in human body core, 2) molecular structure and affinity at inorganic
solid/polymer interface, 3) heat transfer of latent heat storage pellets for high temperature, 4) solid-solution photon
upconversion crystal for improving solar energy utilization efficiency, 5) spin caloritronics by sensitive lock-in
thermoreflectance of thermochromic liquid crystal, and 6) visualization of heat transport in oscillating heat pipesby neutron radiography. The top 3 sessions in which there were the most presentations were “hydrogen, fuel cell,secondary battery”, “boiling and condensation” and “understanding and control of droplet/wetting phenomena”.
The trends reflect recent needs to innovative R&D on greatly efficient energy conversion and conservation
technologies for establishing carbon neutral system. Additionally, heat and mass transfer phenomena are faced tocomplicated systems including multiphase flow, phase change, catalytic and non-catalytic reactions,electrochemistry, electromagnetic, vibration, nano-scale dynamics etc. In the session “workshop on HTSJ
promoted research”, the research activities of groups admitted in HTSJ were reported on the following topics inthis year: 1) heat transfer using microsensors and/or devices, 2) heat and physical environment in bio-cells, 3) heattransfer for solar energy utilization and 4) turbulence heat transfer, combustion and pioneer of complex fluid for
future energy system. Those researches are expected to be greatly promoted and progress under funding for an
innovation of heat transfer in a near future. The session of “introduction of component and technology development
by companies in Tokai district” opened under the organization by researcher/engineers in industrial sector. Tokai
district is one of the largest industrial area in Japan, and several fields of industry, i.e. automobile, machinery, steel,chemical, petrochemical, energy, ceramics, aerospace etc. are concentrated and yield the greatest percentage ofJapanese GDP. Four local companies introduced their technology on 1) low density silicon thermal interface
material, 2) thermal design of printing products and electronic parts, 3) compact and light heat exchanger forvehicles and products working with low power, 4) application of 1DCAE into thermal design. In this symposium,
mutual exchange through earnest discussion were actively performed and could be closed successfully althoughface-to-face meeting had not been held for three years due to COVID-19 pandemic.

Over the past two decades, MEMS (Micro Electro Mechanical
Systems) technology has advanced significantly. Thin film thermal
sensors open the door to unraveling complex heat transfer processes.
Here, we will focus on surface temperature and heat flux measurement
using the MEMS sensors and introduce the latest status.
Microlayer formation characteristics is important for developing a
reliable nucleate boiling heat transfer model which is based on accurate
physical mechanisms. In our studies [1] [2], transient heat conduction
analysis using the local wall temperature measured with a MEMS sensor Fig. 1.1 MEMS sensor for isolate(Fig. 1.1) are applied to estimate the spatial distribution of initial bubble pool boiling [1].
microlayer thickness under pool boiling bubbles and heat transfer
characteristics. Recently, the hydrodynamic characteristics of microlayer
formation in the pool boiling were also investigated based on therelationship between derived initial microlayer thickness and microlayer
formation velocity which is determined by the transient local heat flux
data (Fig. 1.2) [3]. It was found that the trend of microlayer thickness
changes depending on the thickness of the velocity boundary layer
outside the bubble foot developed with bubble growth.
The MEMS technology is beginning to be used in the development ofFig. 1.2 Relation between initial
next-generation high-efficiency automobile engines both for spark- microlayer thickness and velocity
ignition (SI) [4] and compression-ignition (CI) [5]. Wall heat transfer is boundary layer thickness [3].
one of the most important aspects for heat loss mitigation
study of engines. The local instantaneous heat transfer
characteristics were investigated using an originallydeveloped thin-film RTD sensor (Fig. 1.3) [4]. The MEMS
sensor could clearly detect the cycle-by-cycle heat flux (Fig.
1.4). It was found that the local instantaneous heat flux (heattransfer coefficient) had a strong cycle-to-cycle variabilityof the order of 0.1–1.0 MW/m2 (of 0.1–1.0 kW/(m2‫ڄ‬K)), not Fig. 1.3 Three-point MEMS heat flux sensor [4].
only in fired operations but also a motored operation. In
addition, it was shown that the heat fluxes at the adjacentpoints exhibited similar but different values, which indicatesthat there were turbulent eddies of sub-millimeter scale andthey affected the local heat transfer. Since the local
instantaneous heat transfer had quite different characteristics
from the average, advanced design and control based on theunderstandings of the local instantaneous characteristics will
be required for the further improvement of the SI & CI Fig. 1.4 Probability distribution of heat flux fora lean fired condition [4].

The Thermal Engineering Conference 2022 of JSME-TED was held on
October 8th (Sat) and 9th (Sun), 2022 at the Hongo Campus of the Universityof Tokyo. General research presentations, etc. were basically face-to-face, butwere carried out in a hybrid format that also used Zoom. This time, it was thefirst face-to-face meeting in four years (2019 canceled due to typhoon, 2020 and
2021 held online due to COVID-19), and 431 people (including invited
speakers) participated. There were 222 academic presentations, 1 special
lecture, and 2 lectures at the thermal engineering workshop held on the sameday. In addition, two keynote lectures were given as invited lectures fromoverseas (Prof. Xing Zhang, Tsinghua University, China and Prof. Sung Jin
Kim, KAIST, Korea).
The academic presentations of the Thermal Engineering Conference
consisted of General Session (GS) and Organized Session (OS), and this time
there were 28 GS presentations and the remaining 194 OS presentations. The
OS accounts for a large proportion of the conference, and we are grateful to theorganizers for their cooperation in organizing the program. A new OS (OS14:
Nanoscale Thermal Control) was added to the existing 13 OSs. There were 19
academic presentations at OS14, and very lively discussions were held. The Thermal Engineering Conference isa research presentation meeting, where outstanding presentations are awarded the Young Excellent Lecture Fellow
Award. There were many young speakers, and 121 presentations, more than half of the total, were judged. Many
judges, including chairpersons of each session, cooperated in this evaluation.
In the special lecture, Mr. Shigeru Muraki, President of the Clean Fuel Ammonia Association, gave a lecture
titled "Challenges in the Era of Great Energy Transformation - Roles of Hydrogen and Ammonia toward Carbon
Neutrality". The regular thermal engineering workshop was held during the lunch break on the first day. Two
industrial researchers gave lectures on the thermal design of semiconductor memory devices and high-precision
measurement of water-cooling modules. A get-together(opinion exchange meeting) was held on the evening of thefirst day, and 110 people participated. Initially, we hadplanned to hold a get-together at the venue on the Universityof Tokyo campus, but due to the influence of the COVID19, the venue was changed to Tokyo Garden Palace. A
social gathering is an important place for communication
between researchers, and its importance is increasing
especially after self-restraint and online life.
We would like to express our gratitude to the many executive committee members and everyone involved in
the Thermal Engineering Conference 2022 who cooperated in the preparation of the venue and the many students
who cooperated in the venue management during the conference.
