Reavealing and modelling the interplay of intensified heat-transfer and chemical reaction

Energy efficiency is again an important topic in the aftermath of the 2022 energy crisis. It is established that approximately 72% of the world´s primary energy consumption is lost.

Most of the "lost energy" is heat availabe at low temperatures and havesting is a technical challenge that calls for understanding the details of turbulent heat-transfer.

In fact, intensifying heat-transfer is a key to energy-efficient technologies and reactive heat-transfer is a promising but yet unexplored avenue.

This project will forge new detailed understanding and modeling tools for reactive turbulent heat-transfer using impinging jet on a flat plate.

We will use state-of-the-art high-fidelity simulations to capture the details of the process and data-driven techniques to reveal governing features and model the process.

The scientific questions we address are:What are the underlying mechanisms of turbulent cooling/heating with reversible chemical reactions?How do gas density changes modify the near wall flow and coherent structures of an impinging jet?

How to leverage (i) and (ii) for modeling reactive heat-transfer in engineering applications?To that end, we will simulate all important scales at play and reveal details of the heat-transfer enhancement.

Further, the simulations will generate a novel database that will be used  to extract specific features and evidence mechanisms of interest. The database will also open for data-driven modeling and convert the novel knowledge into tools.
