All our technical papers, methods and CFD fundamentals of the Air & Wind domain — wind comfort, aerodynamics, air quality and the digital wind tunnel. Open-access content to understand our studies.
CFD simulation makes the invisible visible: flows, turbulence, thermal plumes and wind comfort. This library gathers our Air & Wind technical papers — from the fundamentals of fluid mechanics to applied studies — to understand, step by step, the phenomena we model every day.
Clear explanations, without unnecessary jargon — for decision-makers and engineers alike.
Each paper is based on studies carried out by our doctor-engineers in fluid mechanics.
Open content to spread the culture of CFD and wind aeraulics.
