Publications

Here you can find all of our publications be they scientific or managerial. Each publication will be available for download and often accompanied by an article to explain its significance and introduce any technical content. No matter your level of computational fluid dynamics or European project expertise, you will know what we’re doing and how it creates impact for our project and beyond.
