At the end of 1982, a small number of colleagues involved in heat transfer research feels the need for an association devoted to advanced studies both in foundation and application in this field. At the initiative of professor E. Lorenzini, the association was initially named ATA, acronym for “Associazione Termotecnica Avanzata”, and held its first congress in 1983, in Trieste. It was really a good success, thus in December 1983 a meeting fixed both the official birth of the new association and changed its name from ATA to UIT, i.e. the “Italian Union of Thermal-Fluid Dynamics”. So, the next Conference, in June 1984, was the first under the name UIT.

UIT has the fundamental aim to contribute to the progress of the Italian research and application of thermal-fluid dynamics, by promoting and enhancing the scientific, professional and social values among its members, also in an international dimension, as well as the formation of new generations of young scientists towards the research work in the field of thermal sciences, heat transfer and their applications. UIT promotes diversity in research and professional activities without regard to race, religion, gender, disability, age, nationality, sexual orientation, gender identity and gender expression.
