Advances in key economical and societal issues facing Europe, like transport, energy generation, climate change, or industrial, environmental and geophysical mixing processes are obstructed by the lack of understanding of turbulence. To date, models fail to explain many fundamental features of turbulence, from boundary layers and particle transport, to heat transport and turbulence in complex and quantum fluids. This has led several European countries to fund new large-scale turbulence facilities, unsurpassed in flow properties and measurement technologies. Currently these are not easily accessible to the larger EU scientific community. This inhibits the rapid advancement of research across Europe and hinders the optimal use of the resources, and their impact on the development of new advanced technologies and solutions.Recognizing this deficiency, the leading groups in turbulence research with members from 9 countries propose to form the European High-performance Infrastructures in Turbulence (EuHIT) within the Integrated Infrastructure Initiative (I3). 14 Top-notch European infrastructures agreed to provide the research community with transnational access to their facilities. Joint research activities of the consortium will innovate and explore new fundamental technologies that will ensure efficient and joint use of these research infrastructures by creating harmonised and enhanced interfaces, improving data processing methods, and optimizing the quality and increasing the quantity of the services provided to researchers from academia and industry alike. A networking and educational program will be established to foster cooperation among research infrastructures and the scientific community, to train the next generation researchers in using the most modern equipment and data analysis techniques, and thus to develop a more efficient and attractive European Research Area.
