Zois Award can be given to a researcher in the Republic of Slovenia, who has made through his achievements a lasting contribution to the development of scientific research and development activity in the Republic of Slovenia. This time, the Committee of the Republic of Slovenia for bestowing prizes and awards for outstanding achievements in scientific research and development activities awarded Prof. Dr. Matevž Dular, who received the Zois Award for important contribution to understanding the phenomenon of cavitation. Prof. Dr. Matevž Dular is a full professor at the Faculty of Mechanical Engineering of the University of Ljubljana, where he researches in the field of engineering fluid dynamics, and especially in the field of cavitation – evaporation of water due to a sudden pressure drop.

Cavitation is considered to be one of the most pressing problems in the operation of turbine machines, since it causes vibrations, noise, reduction of efficiency and damage to the blades of the machine.

Particularly should be stressed his contribution to understanding cavitation aggressiveness. He proposed a physical explanation of the process of cavitation erosion, which was previously based solely on empirical relations. He later experimentally confirmed his theoretical model of cavitation erosion and incorporated it into the methodology of computational fluid dynamics, which can be used to predict the occurrence of damage in advance.

As part of his work for the European Space Agency (ESA), he developed several new models for the survey of evaporation and condensation in rapidly changing pressure fields, and as a first he pointed to the possibility of direct measurements of temperature fields in cavitating flow, which makes it possible to optimize the performance of rocket engine turbo pumps.

Not least, his contribution to understanding cavitation aggressiveness in a new field – in the field of use of cavitation, where it is used to kill viruses, bacteria and pharmaceuticals – should be emphasized. In this field, Prof. Dular also obtained the prestigious European Research Council (ERC) project, which explores the basic mechanisms of the effect of cavitation on contaminants. The CABUM project – Investigation of the mechanisms of interaction of cavitation bubbles with contaminants will lead to a better understanding of the physical background of the occurrence of cavitation that could be used in the future for environmentally friendly potable and waste water treatment.

We sincerely congratulate him on his achievements in science and the reward he has received!
