Dr. Antonios Hatziapostolou is an Associate Professor at the Department of Naval Architecture, School of Engineering, University of West Attica, Greece. He received his Diploma in Mechanical Engineering from the Mechanical Engineering Department, School of Engineering, University of Patras in 1982, and his Ph.D. in the study of flow and combustion in direct-injection diesel ngines from the Imperial College of Science, Technology and Medicine, University of London, 1991. His main research interests include the study of the performance of marine dual-fuel engines, combustion investigations of gaseous, atomized liquid, and pulverized solid fuels to improve efficiency and reduce pollutant emissions in various systems, such as industrial cement kilns and internal combustion engines, and fluid mechanics studies in diverse applications, such as the flow in solar collectors, fuel cells and the laser-induced deposition of Newtonian and non-Newtonian fluids related to electronic and biomedical uses, combining CFD with experimental measurements.
