PRESENTATION VIDEO

He was born on 16 May 1989 in Šibenik. He graduated in 2012 from the undergraduate and 2015 from the grad- uate studies in mechanical engineering at the Faculty of Mechanical Engineering and Naval Architecture of the University of Zagreb (FSB). He also received his PhD from FSB in 2023. In addition, during his studies, he participated in the Erasmus program and spent five months at the Smart Interfaces Center of the Technical University of Darm- stadt (Germany). After graduating, he worked for a short time at the company Creative Fields in Zagreb, and since 2016 he has been working at FSB, where he is currently a senior assistant at the Chair of Technical Thermodynam- ics of the Department of Thermodynamics, Thermal and Process Engineering. He has received several academic awards.

In lieu of development of the computational mod- els for boiling flow, an initial step is the solution of Stefan problem - a planar interface evaporation case for which there exists an analytical solution for transient interface advancement and the temperatu re field. However, the original solu- tion to Stefan's problem involves a constant that

has to be numerically obtained. To mitigate this, a quasi-steady solution in Cartesian coordinates comes in handy. In this paper, the applicability of quasi-steady model is investigated for different wall superheats by comparison with the analyt- ical solution and numerical simulation.
