Current Advances in Turbulence and multiphase flowS - 24CATS

Okinawa, Japan, 16-19 April, 2024


Summary & Goals
Turbulent flows are ubiquitous in nature and industrial applications. They are, however, notoriously difficult to predict, owing to the non-linear and multiscale dynamics at play. Despite over a century of intensive efforts, understanding turbulent flow of simple fluids remains the last unsolved problem of classical physics. The situation is further complicated when considering multiphase flows. Indeed, turbulent fluctuations can profoundly affect the dynamics of the dispersed phase, which in turn, can modulate the turbulent flow in complex and sometimes unpredictable ways. Multiphase turbulent flows are commonly found in many environmental processes (e.g., seed/pollutant/microplastics dispersal) and engineering applications (e.g., combustion or papermaking). In sufficiently dilute conditions, it is often assumed that the flow is not appreciably altered by the presence of the dispersed phase. By contrast, in the non-dilute condition, a significant alteration of the turbulent flow in its qualitative and quantitative features can occur, with potentially dramatic consequences, e.g., on the energy distribution across the various scales of motion, or drag enhancement/reduction effects. Understanding the essential mechanisms governing the modulation of multiphase turbulence, therefore, represents a subject of paramount importance, both at a fundamental level and in view of numerous applications. This workshop will gather world experts in turbulence and multiphase flows to discuss the most recent advancements in the two fields, promote the exchange of state-of-the-art knowledge, and seed future collaborations.

Code of Conduct

We are committed to making our workshops (workshop(s) organized by OIST, hereinafter “our workshop(s)”) an inclusive space for sharing ideas and knowledge. We will not tolerate disrespectful communication, discrimination, harassment, or bullying in any form. As such, all participants attending our workshops are required to comply with this Code of Conduct. To provide all participants the opportunity to benefit from our workshops, we at OIST are dedicated to a positive, safe and harassment-free experience. Harassment in any form is specifically prohibited.

What is Harassment?

Harassment involves continued antisocial or unreasonable actions that violate a reasonable person’s personal rights and/or dignity and cause mental suffering, and thus worsen the person’s environment or make him/her anxious about participation. Behavior that is acceptable to one person may not be acceptable to another, so we ask that you use discretion to be sure that respect is communicated. Harassment intended in a joking manner nevertheless constitutes unacceptable behavior. Speech that is not welcomed or that is personally offensive, whether it is based on gender, age, sexual orientation, mental or physical disability, ethnicity, national origin, religion etc. will not be tolerated.

If you are being harassed, notice that someone else is being harassed, or have any other concerns, please bring this to the immediate attention of the organizers. If you wish to report an issue concerning the organizers, you can contact the Conference and Workshop Section directly and submit a confidential report by sending an email to or submitting a report through the webform. All complaints will be taken seriously and responded to by the Provost promptly. Confidentiality will be maintained to the extent that it does not compromise the rights of others. Individuals found in breach of this Code of Conduct will be dismissed from the workshop immediately. Retaliation for reporting harassment is also a violation of Code of Conduct, as is reporting an incident in bad faith.


Registration fee
20,000 JPY

Registration deadline
February 29, 2023.

If you would like to partecipate to the workshop and give a contributed talk or a poster presentation, then you should fill out the application form no later than December 31, 2023. Participants with selected contributions will be notified by email before mid January.

 Hotel and Travel Agency Scammers

Workshop organizers and invited speakers are often contacted by number of "travel agencies" to which OIST is not related, based on the publicly available information on the web. Please refrain from replying to those agencies unless OIST organizers or secretariat have explicitly contacted you beforehand. When in doubt, please send a copy of any email communication to the OIST Conference and Workshop Section:


1. Application Deadline
Please ensure that your application is submitted by December 31, 2023. Late submissions might not be considered.

2. Selection Process
After the application deadline, our team will carefully review all submitted applications. In the event that the number of applications exceeds the available spots, participants will be selected accordingly.

3. Notification of Acceptance
Once the application review is complete, we will notify all applicants about the status of their application, expected by mid January . If you're selected to participate, you'll receive a link to a registration form to provide detailed information. Registration will start in February and close at the end of the month.

4. Commitment
If you are accepted as a participant, we kindly request your commitment to attend the workshop sessions punctually and actively engaging with the content and your fellow participants.
