From January to April, Antoine Courouble, a PhD student from INSA Lyon, has been conducting research work in the Department of Thermal Sciences in cooperation with the Division of Refrigeration and Heat Pumps. The internship is the result of a long-standing collaboration between Bartosz Zajączkowski, Bartosz Zajączkowski, PhD, DSc, Assoc. Prof., and the scientific team of Prof. Jocelyn Bonjour of CETHIL, INSA Lyon. Previously, PhD students from the Division of Refrigeration and Heat Pumps (including Wiktoria Lada, MSc and Barlomiej Nalepa, MSc) had their internships in Lyon. After a series of research internships of students from French universities (Mr. Rémi Vandevelde and Benoît Villette, as well as Ms. Natacha Chaline), this year we host for the first time a doctoral student carrying out research tasks related to the completion of a dissertation.

Tomasz Halon, PhD, and Antoine Courouble

The Laboratory of Multiphase Processes Intensification has been conducting research on the topic of boiling natural refrigerants at low pressure for many years, including the work of Tomasz Halon,PhD (boiling on developed surfaces) and Wiktoria Lada, MSc (droplet evaporation).

Mr. Antoine Courouble's research on the effect of surface material and droplet size on the evaporation of natural refrigerants under vacuum is part of the focus of ongoing work in the Laboratory of Multiphase Processes Intensification. Over the next three months, he will focus on the study of droplet evaporation of water and alcohols, which will complement his research at INSA Lyon laboratories. The realization of this part of the research tasks, particularly concerning alcohols, will be possible because of the experimental setup for volumetric boiling of natural refrigerants under subatmospheric conditions that the laboratory is equipped with.
