Salamanca, Gto., April 25, 2017.- The international projection of the Division of Engineering of the University of Guanajuato (UG), attracts more students from different countries to study postgraduates with quality recognition. So, the first Congolese student finished his doctorate in Mechanical Engineering.

Jean Fulbert Ituna Yudonago was born in Kinsasha, capital of the Democratic Republic of Congo, where he studies in the Instituto Superior de Técnica Aplicada (ISTA). In January 2010, he arrived at the Division of Engineering to study the master degree in Thermofluids Mechanics and at the end, he was admitted in the doctorate in Mechanics, which is taught at Campus Irapuato Salamanca, with a scholarship from the National Council of Science and Technology.

His doctoral exam was the presentation of his research "Energetic improvement based in a dynamic model for a trans critic steam compression installation", accompanied by his thesis advisors, Ph.Ds. Juan Manuel Belman Flores and Francisco Elizalde Blancas.

His doctoral work is focused on the numeric model and simulation of the main components of the trans critic steam compression installation which include a gas cooler, exchanger of intermediate heat and evaporator, with the purpose for each model to predict the transitory behavior of the relevant component during the experimental trans critic installation under study, with the purpose to propose energetic improvements in the same.

To finish his project, he made a short residency with Ph.D. Ismail B. Celik, a renowned researcher of fluid dynamics, at West Virginia University, US, where the research models were developed mathematically and geometrically and processed in the software ANSYS Fluent 14.0. The analysis was based in the transitory behavior of the thermo-physic properties, as well as the parameters of heat transfer.

"I learned a lot in the University of Guanajuato and had a great growth as student" mentioned Jean Fulbert, who predicts to dedicate to research, specially seeking to improve in the thermo-energetic systems, since the performance problem that haunts the trans critic systems in refrigeration, the use of the dynamic modeling in the search for energetic improvement in the same can be a promising option.
