Conference Report: The 25th International Congress of Theoretical and Applied Mechanics(ICTAM 2020+1) Aug 20-27, 2021, Online.
by Shu TAKAGIThe 25th International Congress of Theoreticaland Applied Mechanics (ICTAM 2020+1) was held asa fully virtual congress from 22 to 27 August, 2021. It
was initially scheduled one year before (Aug. 23-28,
2020) and should have taken place in Milano, Italy.
But Covid-19 disaster caused a one-year extension,and it was finally decided to transform into the virtual.
In spite of online event, it was very successful with
1740 registered participants, 1035 keynote and oralpresentations, 388 short oral presentations with posters,
6 mini-symposia, 46 thematic sessions, 16 sectional
lectures, 4 plenary lectures, 59 participating countries.
The congress was chaired by Prof. Alberto Corigliano,
Professor of Politechnico di Milano with the supportof Italian Association of Theoretical and Applied
Mechanics.
ICTAM is a special conference organized by the
IUTAM (International Union of Theoretical andApplied Mechanics). It is one of the oldest conferencesin the field of mechanics. It was started with Prof.
Theodore von Kármán, professor in Aachen(Germany), who held a conference in Innsbruck in
September 1922 to discuss questions ofhydrodynamics and aerodynamics. The first IUTAM
congress was held in Delft in the Netherlands in 1924.
So, the conference is close to its one hundred years
anniversary. Starting at 1924, ICTAM has been held
every four years. In addition to this ICTAM, there aremany satellite symposiums organized by IUTAM,
which is called IUTAM symposiums, and you can findthe information of upcoming events in the following
websites.
https://iutam.org/accueil/upcoming-events/
So, as you can see from the above explanation,
ICTAM is like an Olympic of mechanics, where
researchers in many different topics of mechanics get

together and have fruitful deep discussion in theircontents. Here, I will pick up some of the presentations
which are related to our multiphase flow society.
The 25th ICTAM had a Plenary Opening Lecture
and a Plenary Closing Lecture. The Opening Lecture
was related to solid mechanics (Bioinspired
Nanomechanics by Prof. Nicola Maria Pugno,
University of Trento). The Closing Lecture is for Fluid
Mechanics, (Rheology of Dense Granular Suspension,by Prof. Élisabeth Guazzelli, University of Paris.). The
contents are how to model a macroscopic motion ofdense granular suspension from microscale modelingof each particle. She explained many different
approaches for this problem.
They have 18 keynote lectures assigned inminisymposia. Prof. Howard Stone (Princeton
University) gave the keynote lecture with the title of“Particle motion nearby rough surfaces”. In this talk,mobility of a spherical particle was described as afunction of roughness and surface shape. It was very
interesting to see how the randomness of the surfaces
appears in the trajectory of the particle. It wasemphasized that the feature of surface roughness
amplifies the in-plane and perpendicular motions. The
analysis can be utilized to understand the behaviors of
microswimmers near corrugated walls.
I was also very much impressed by the keynote
lecture by Prof. Genta Kawahara (Osaka University).
The talk was related to the invariant solution of the
turbulent flows. It is the topic for single phaseturbulence and the solutions will not be available tomultiphase flow turbulence. But the way of thinking
to understand complicated non-linear dynamics
inspired me a lot. The series of studies have been
conducted with the collaboration of Prof. Uhlmann(Karlsruhe Institute of Technology), who is wellknown for the large-scale simulation of particulate
turbulent flows.
By the way, talking about the turbulent flows, Prize
Plenary Lecture of the 2020 Batchelor Prize winner in
Fluid Mechanics was given by Prof. Alexander J.
Smits (Princeton University) with the title of“Measurements in Wall-Bounded Turbulence”. Hegave the impressive talk about the extremely carefulmeasurement for turbulence. At the end of his talk, heshowed interesting cartoon and explained that thecomputer simulations are getting more and more
important. It was just a support to stand up with twolegs of experiments and theory. Then, it became an
important third legs which is nearly equivalent
contributions. Now it has become the muscle tostrength the experiment and theory. The Batchelor
Prize is thought to be the most distinguished award in
the field of Fluid Mechanics. The first winner was Prof.
Haward Stone (2008), the second was Prof. Detlef
Lohse (2012), the third was Raymond E. Goldstein,
and this time is the fourth and was Prof. A. Smits. Both
Prof. Stone and Prof. Lohse have great contribution to
the field of multiphase flows. Prof. Goldstein has beenworking on physical aspects of multicellularity, whichcontains the topic of collective behaviors of
microorganisms. Since this topic is also the topic ofdispersed multiphase flows, we can say that threeamong four topics of Bachelor Prize are related to themultiphase flows. Noted that Prof. Lohse was theplenary lecturer of the ICMF-Yokohama, 2004.
Getting back to the talk in ICTAM, I was also very
interested in the talk by Dr. Jacques Magnaudet(CNRS, France), who gave the talk about two bubble
interactions rising inline. He discussed the different
type of motions called DKE (Drafting-KissingTumbling) and ASE (Asymmetric Side Escape )For Japanese researchers’ talks related to themultiphase flows, Prof. Minori Shirota gave the talkwith the title of “Thermally-driven bubble oscillationin an impacting drop.” They observed a unique circular
subcooled boiling in an impacting water drop on aheated solid surface using high speed camera andrevealed that evaporation of microlayer and thecondensation on the subcooled liquid play importantroles for bubbly dynamics. Prof. Masako SugiharaSeki
gave the talk with the title of “Inertial focusing of
spherical particles suspended in square channel flows.”
They had found the very interesting characteristics
about the stable position of a spherical particles in across section of the square channel. To understand thephenomena, they compare the experimental andsimulation results in the present talk. There are one
oral and two poster papers from the group of Prof.
Yoshiyuki Tagawa. All of them are very interesting inthe sense that they have simple experiments explainedby the simple mathematical model with the important
physics sophisticatedly involved. For example, oralpresentation was given with the title of “Terminal
extensional viscosity of dilute polymer solution using
CaBOR-DoS system”, which discuss the very thin

liquid thread becoming unstable due to the effect of
surface tension and forms a beads-on-a-string andpinch-off.
At last, I would like to mention what was goodwith the present fully virtual events. The presentation
was given in two ways, which is worth for explaining.
The plenary and keynote lectures were given with realtime online style. For other regular oral presentations,pre-recorded video was played for 5 minutes. Fig.1
shows the snapshot of the pre-recorded video of mypresentation. The speakers were expected to attend thesession while the presentation videos were shown.
After watching the video, the audience can give thequestions to the speaker and they are supposed toanswer them. In addition to this presentation, thespeakers need to prepare the long version video as
supplementally materials, which audience can watch
any time they would like to watch. This system works
very fine for the audience who would like to know
more details of the study, although the speakers spend
more time for the preparation of two movies (5minutes short version and 15 minutes long version). It
should be also noted that all the presentations wererecorded, and we could watch them repeatedly until
the end of December 2021; 4 months after the congress.

This is a great benefit of the fully virtual congress.
The next ICTAM will be held in Daegu, South
Korea, in 2024. It will be the special event to celebrate
the 100 years anniversary of ICTAM. I look forward toseeing many of you there.
