The final defense of PhD thesis was taken on 4th April in Heat Transfer and Fluid Flow Laboratory. Their thesis came to defend Helena Votavová and Erik Bartuli.

Helena Votavová focused on ‘Development of New Approaches in Descaling in the Continuous Production of Steel Using High-Pressure Water Jet’. The thesis summarizes general and up-to-date knowledge of descaling during the continuous production of the hot-rolled steel and proposes further streamlining of this process in industrial production. The thesis was supervised by associate professor Michal Pohanka.

Erik Bartuli focused on ‘Optimization of Heat Transfer Surfaces of Heat Exchangers’. The thesis focuses on metal and plastic heat exchangers. The main object of the research is the optimization of heat transfer surfaces for increase of heat transfer characteristics of heat exchangers. A computer modeling via ANSYS and experimental research were used for this purpose. A crosswinding technology for polymeric hollow fiber heat exchangers (PHFHE) producing was developed based on modeling and experimental results. An experimental setup used for pressure tanks winding was modified for PHFHE mass production. The thesis was supervised by professor Miroslav Raudenský.

Erik Bartuli determined to defend his theses

Both thesis were successfully defended. Congratulations to Dr. Votavová and Dr. Bartuli. We wish them great success in the future.
