Scientific Calendar Event



Description
An ICTP-IAEA Virtual Meeting

​The course will provide graduate students and professionals with theoretical foundations and examples for application of computational fluid dynamics (CFD) modelling in nuclear engineering. The need for high fidelity nuclear reactor thermal hydraulic simulations has led to increased application of the CFD codes that are prevailing substitute of currently established one dimensional system thermal hydraulics codes and coarse mesh sub-channel analyses codes. Therefore, CFD constitutes the “third approach” in the philosophical study and development of the whole discipline of fluid dynamics. Combining the power of experimentation and theory, this approach has made possible the accounting of flow fields in complex geometries. This course will outline these aspects and provide the participants with hands-on examples.
 
The course will build a theoretical understanding on the science of CFD and its applications in nuclear engineering supported by various hands-on practical examples. Knowledge transfer will be facilitated between the international experts as lecturers, and students, professionals and engineering analysists, as participants. Given that the CFD codes, which have empirical models for simulating heat transfer, turbulence, single-phase and multi-phase flow, are currently available along with general application-oriented training in their use, the focus of this course is on providing the required background about the embedded models with the goal to improve the participants’ theoretical foundation for CFD applications in the area of nuclear engineering.
 
Along with the theoretical lectures and hands-on learning examples, the course will include comprehensive overview of the history of CFD development and its applications in nuclear engineering, including development, status, and challenges.
 
As part of the application, participants should submit min 1-page to max 2-page original essay, covering one of the course topics of their choice. The best five essays will be selected for participants to present at specially designated session (for which they will need to develop up to 10 slides and present in no longer than 10min time slot) – other participants and lecturers will be asked to vote. At the closing of the course, the organizer will announce the best voted presenter.
