Breathney: A modular design toolbox for an affordable ventilator with full functionality

The Covid-19 pandemic is still progressing globally and a small but significant fraction of patients need mechanical ventilation at some point. Although some countries have sufficient ventilators, there are indications of a future global shortage of such devices.


High-fidelity surrogate wind data

The objective of this project is to create a modelling framework for high-fidelity surrogate wind data. This work is largely the PhD project of Daniele D’Ambrosio whom I supervise with prof.  Tim De Troyer.

Interaction of closely-spaced vertical-axis wind turbines

Vertical-axis wind turbines, when placed close together, have an improved power production and very interesting aerodynamics. The experimental side of this project is the PhD project of Antoine Vergaerde. The computational side of the project is taken care of by Greeshma Boohalli Shivamallegowda. Both Antoine and Greeshma are supervised by Tim De Troyer and myself.

Distributed wind energy and small wind turbines.

I have been working on distributed wind energy since 2007. Jochem Vermeir’s PhD thesis summarises a lot of the work that we did back then. I was involved in IEA Wind Task 27 on Small wind turbines in strongly turbulent environments and am currently involved in IEA Wind Task 41 on distributed wind.
