DROPIT Reseachers participated at ILASS Europe 2023 Conference, Neaples, 4th – 7th September

A group of DROPIT Ph.D. students together with colleagues from ITLR attended the European Meeting on Liquid Atomization and Spray Systems (ILASS Europe). The presendted reseach work was a great success both for the Ph.D. students themselves and for the DROPIT project. Furthermore, our associate researcher Verena Kunberger won the best paper award for early carrier researchers.

DIPSI Workshop 2023 - Droplet Impact Phenomena & Spray Investigations, Bergamo, 16th June 2023

Also this year, the DIPSI Workshop on "Droplet Impact Phenomena and Spray Investigation" was a great success! The latest findings on droplets and sprays in a variety of research areas and industrial applications were shared. A big thank you to all the participants for their valuable contribution.

Deshalb ist Tropfenforschung wichtig (in German)

Tropfen kommen in vielen Bereichen des alltäglichen Lebens vor: beim Lackieren von Oberflächen oder dem Aufbringen von Pestiziden. Das zeigt, wie wichtig es ist, die Physik der Tropfen zu verstehen. Julia Nestlen im Science Talk mit der Ingenieurin Dr. Anne Geppert vom Institut für Thermodynamik der Luft- und Raumfahrt der Universität Stuttgart.

Tropfenforscherin Anne Geppert (in German)

Team and Institutes

The International Research Training Group (IRTG) DROPIT is a collaboration between the universities of StuttgartBergamo and Trento. The IRTG has fifteen principal investigators. Around 15 doctoral researchers and several postdoctoral researchers are currently working together to solve droplet dynamics problems.

Further Information


DROPIT is a research training group focusing on the study of droplet interaction phenomena. The objective is to understand how micro-scale transport processes affect macroscopic flow properties in three  thematic research  areas (TAs): drop-gas interaction (TA-A), drop-wall interaction (TA-B) and drop-liquid interaction (TA-C). A key feature is the interdisciplinary approach, which envisages the synergic integration of experimental (X-ray micro-CT, micro-PIV), numerical (DNS, discontinuous Galerkin schemes, Direct Simulation Monte Carlo), and analytical methods (heat and mass transfer models for evaporation, interactions).

Further Information

Qualification Programme

The qualification programme fosters the development of each doctoral student into an independent researcher. Specialised courses impart knowledge in droplet-related topics, while soft skill courses train the doctoral researchers to conduct and present their research in an effective way. Visiting researchers and an international summer school complement the courses.
