Technical papers, fundamentals and CFD simulation videos : everything you need to understand flows, heat and safety — from the data center to industry, in open access.
CFD simulation makes invisible phenomena visible : airflows, heat transfer, smoke and pollutant dispersion. This library brings together our technical papers and our fundamentals, drawn from real projects led by our PhD fluid-mechanics engineers — for decision-makers and engineers alike.
Clear explanations, without unnecessary jargon — to decide and to design.
Every paper draws on concrete studies carried out by our engineers.
Open content to spread the culture of CFD and fluid mechanics.
