**About the Editor**

**Artur Bartosik**, Dr. Hab. Eng. Prof. KUT, is an appointed researcher and academic teacher in the Department of Production Engineering at the Kielce University of Technology. Together with his team, he works to establish the structure for university-wide multidisciplinary collaborations in fluid mechanics, rheology, and renewable energy. His scientific interests are focused on experiments, modellings, and simulations of single- and two-phase flows, including convective heat transfer. As a researcher, Artur spent 2 years at the University of Saskatchewan in Canada and also spent some time at Ilmeanu Technical University in Germany. He is coeditor of *WSEAS Transactions on Fluid Mechanics* and Ass. Editor of the *Journal of Hydrology and Hydromechanics*. He gives lectures on fluid mechanics; heat transfer; fluid flow machinery; hydrotransport; renewable energy sources; transnational technology transfer; and applied fluid mechanics.
