Welcome letter
Dear Conference Delegate,
Welcome to the 37th UIT Heat Transfer Conference, organized by the Department of Industrial Engineering at University of Padova (Italy) and held at Centro Linguistico di Ateneo, Padova, on June 24-26, 2019.
The annual UIT Conference, which has grown over time, is held in Padova for the first time. The scope of the conference covers a range of many topics in theoretical, numerical and experimental heat transfer and related areas, ranging from energy efficiency to nuclear plants.
This year the UIT Conference includes an International Symposium on “Refrigerants: heat transfer and applications”. This Symposium will be held on June 26, 2019, which is the first World Refrigeration Day and is organized in collaboration with CNR, Istituto per le Tecnologie della Costruzione.
In this conference edition, 99 papers were contributed plus 3 keynote lectures and 5 invited lectures. We hope this conference will be a useful occasion to stimulate discussion, improve the understanding of heat transfer and related phenomena, present the state of the art of some topics, discuss emerging trends and promote collaborations.
A special thank is due to the Organizing and Scientific Committees, to the Sponsors and to all the Participants.
Davide Del Col and Luisa Rossetto

SOCIAL PROGRAM Opening ceremony and welcome cocktail The opening ceremony will take place at the congress venue on Monday 24 June at 10.15. The welcome cocktail will be held in the external terrace of the Palazzo della Ragione on Monday 24 June, at 20.00. Palazzo della Ragione is 2 km far from the conference venue. Palazzo della Ragione The building, with its great hall on the upper floor, is reputed to have the largest roof unsupported by columns in Europe; the hall is nearly rectangular, its length 81.5 m, its width 27 m, and its height 24 m; the walls are covered with allegorical frescoes. The building of Palazzo started in 1172 and finished in 1219. Inside the huge hall, which was rebuilt in 1430 and can seat up to 1500 persons, there is a th large 15 -century wooden horse, a copy of Gattamelata's horse.
Social Dinner The Social Dinner will take place at the “Castello del Catajo” on Tuesday 25 June. A transfer service by bus will be available, departing at 19.00 from the congress venue, return at the end of the dinner. Castello del Catajo The Catajo Castle, built on the slopes of Montenuovo, is an imposing complex whose exterior resembles a military fortress. Its wide terraces offer a splendid view of its large garden. The Catajo Castle was built between 1570 and 1573 by Pio Enea I degli Obizzi, from a French family of “soldiers of fortune” who, attracted by the beauty of the Euganean Hills, decided to build a palace that would represent the glory of the Obizzi family. After the extinction of the family, the castle passed first to the Estensi family, then to the Habsburg who used it as a hunting estate. Then, in 1929, it became the property of the Dalla Francesca family, who sold it at the end of 2015. The structure has impressive proportions (there are more than 350 rooms). It is decorated in the interior with a series of frescos painted by Gianbattista Zelotti, student of Paolo Veronese. The wide park surrounding the castle has many century-old trees and notable vegetation.
