Job description

Turbulent multiphase flows encompass some of the most complex phenomena in fluid dynamics and their analysis presents a great challenge for even state-of-the-art experimental and numerical methods. Machine learning and artificial intelligence, currently revolutionizing the fluid dynamics field, can be powerful tool in such cases. However, they remain limited to simple scenarios involving single-phase flows. Our primary goal is to tackle the challenge of data-driven low-dimensional modelling of multiphase flows. The focus will be on a specific scenario of friction drag reduction in liquid flows by gas injection.

In this PhD project, you will work on the experimental characterisation and analysis of such flows, exploiting various flow measurement techniques (including particle image velocimetry, pressure and drag measurements). Optimal data collection and representation of different flow states will allow you to then develop state-of-the-art data-driven models for reduced-order modelling of such flows, with a view towards future control strategies.

As a PhD student, you will be part of two vibrant teams of researchers within the Multiphase Systems (MS) and Learning for Autonomous Control (LAC) sections, with diverse backgrounds and expertise. Your supervisors will be Dr. Angeliki Laskari and Dr. Cosimo Della Santina within the Process & Energy and Cognitive Robotics Departments.
