Research themes

My research focuses on four main themes: multiphase flows and mixing, reactive transport and catalytic media, artificial intelligence and advanced modeling, and process intensification and energy-efficient reactor design. Through both experimental and computational approaches, I investigate fluid mechanics, heat and mass transfer, and reaction phenomena in chemical reactors, aiming to improve the understanding, modeling, and optimization of transport and reactive processes.

 

Multiphase flows and mixing

I am particularly interested in linking experimental investigations, Computational Fluid Dynamics (CFD), and artificial intelligence methods, including Physics-Informed Neural Networks (PINNs), Reinforcement Learning (RL), and stochastic approaches, to better understand mixing phenomena, fluid–solid thermal interactions, fluid–structure interactions (FSI), and particle aggregation in static and dynamic chemical reactors.

Reactive transport and catalytic media,

A major aspect of my work concerns mixing and transport phenomena in porous and structured domains, particularly in the presence of catalytic coatings. I am interested in the numerical optimization of mixing and reaction processes in catalytic porous media, with a focus on improving reactor performance and efficiency.

I also investigate the coupling between transport phenomena and chemical reactions, including both homogeneous and heterogeneous reactions. These reactions can significantly affect local temperature and concentration fields, as well as the physical properties of the reacting media. Understanding these interactions is essential for the accurate modeling and optimization of chemical reactors.

 

Process intensification and energy efficiency

In addition, I am interested in heat transfer phenomena in chemical reactors, both experimentally and numerically, including selective heating strategies in structured systems and their impact on reactor performance.

More broadly, my research contributes to the field of process intensification, aiming to develop more efficient, sustainable, and energy-saving chemical processes through improved reactor design, enhanced transport phenomena, and advanced modeling approaches.
