About
Temistocle Grenga is a Lecturer in Computational Fluid Dynamics for Aerospace at the University of Southampton since February 2023. He is an expert in numerical simulation of turbulent reacting flows and data-driven modeling.
His research spans from numerical methods, numerical simulation of turbulent reacting flow, and machine learning modeling.
He received the Ph.D. in Aerospace and Mechanical Engineering at the University of Notre Dame (USA) in 2015. Before joining the University of Southampton, he has been Postdoctoral Research Associate at Princeton University (USA) from September 2015 to August 2018, and at RWTH Aachen (Germany) from September 2018 to January 2023, where he was also Leader of the Multiphase Group and the HPC Group.

Current research
My research focuses on the simulation of turbulent reacting flows, with the aim of understanding the physical mechanism driving this intricate interaction between fluid dynamics, chemistry and heat release.
The current prominent activities are:
- Direct numerical simulation of hydrogen combustion through the use of GPU-based solver (NekRS) and High-performance computing facilities
- Large eddy simulation models for hydrogen combustion
- Generative adversarial network -based models for turbulence and transport phenomena
- Convolutional neural network modeling of hydrogen combustion
- Flashback phenomena for hydrogen combustion in pratcal applications
- Reduced order models for mutiphase flows
