Liquid atomization occurs in many processes and it can be achieved by different approaches. For example, pressure swirl atomizers or liquid dispersion on the mesh. Airflow in both processes is an important parameter because it affects the motion of droplets. This fundamental research aims to add missing information about the behaviour of droplets in low turbulent airflow. Results of this experimental and numerical work can serve for designing more efficient devices, e.g. sprays in CO2 capture or sprays in turbines and engines.

Description in English
The aim of the project is to create a competition for student research grants and its pilot verification. The creation of a new competition will contribute to the development of cross-sectional skills of doctoral students, and thus acquire competencies for work in science and research in the future and increase their success in submitting scientific projects to national and international competitions.
