Introduction
We are happy to confirm that the online PhD symposium will be organized from Monday 18 May until Wednesday 20 May 2020. Prominent lecturers in three application fields of fluid dynamics will give a keynote lecture opening each day of the symposium.
During the 11th PhD symposium, the VKI graduate students will review the doctoral research carried out in the three departments of the Institute: Aeronautics and Aerospace, Environmental and Applied Fluid Dynamics, and Turbomachinery and Propulsion.
The first-year PhD students will present a short pitch of maximum 5 minutes on their research plans and some preliminary results. Their posters are available for download on the programme tab.
The second-year students will give a 15-minute talk on their research activities and progress results followed by 5 minutes of questions.
The third-year students will give a 20-minute talk followed by 5 minutes of questions.
The talks are organized in sessions according to the following topics:
- Rarefied and Plasma Flows
- Aerothermodynamics
- Numerical Methods
- Aerothermochemistry
- Environmental Flows and Safety
- Liquid Metal and Industrial Flows
- Liquid and Solid Propulsion
- Shape Optimization

Programme
Monday 18 May 2020 (online)
09:00 Keynote Lecture
Prof. Isabelle Gallagher, École Normale Supérieure, University Paris-Diderot, Paris, France
Deriving fluid mechanics equations from particle systems
Abstract: Depending on the scale at which one observes a physical phenomenon, it can be described very differently. For instance air is constituted of a gigantic number of molecules that are in constant motion, following the laws of classical mechanics (just like billiard balls) but this microscopic description is often less useful for pratical purposes than the macroscopic description of its temperature, velocity, etc. We shall see how mathematical analysis enable one to reconcile both descriptions, microscopic and macroscopic. We shall on the way understand why the macroscopic motion can be irreversible in time, despite the fact that the miscroscopic motion is reversible.

Recent results on Deep Reinforcement Learning applied to flow control and optimal design
Abstract: Fluid Mechanics features many challenging problems, due to the combination of non-linearity and high dimensionality that arises from the Navier Stokes equations. Such problems include, to name but a few, Active Flow Control (AFC) and Optimal Design (OD). While both topics have been the focus of much research over the last 40 years, traditional methods based on linearization of the system and gradient descent face many challenges when applied to Fluid Mechanics problems. Therefore, new tools may be required to provide further improvements on those topics.
In this talk, we will offer a brief introduction to the main ingredients behind Artificial Neural Networks (ANNs) and Deep Reinforcement Learning (DRL), and give a high-level overview of how such methods work. Following this, we will present recent results of DRL in AFC. In particular, we will discuss why recent milestones achieved in AFC are promising for real-world applications, and how these compare to more traditional methods such as the adjoint method. Finally, we will provide a brief overview of available resources, including Open Source code packages and example code showcasing recent applications, that may help people new to the field to start working on such topics.
