Dr. Vasileios Fragos is Lecturer at Department of Hydraulics, Soil Sciences and Agricultural Engineering of Aristotle University of Thessaloniki. He has received MSc and Ph.D. in Agricultural Engineering of Aristotle University of Thessaloniki. His research focuses on computational fluid mechanics, thermodynamics and pump systems. Particularly, he is a specialist in fields of computational techniques for simulation of two or three laminar or turbulent flow (solving of Navier-Stokes equations, finite element method, statistical analysis, and spectra analysis), writing of finite element code and numerical simulation of internal and external environment (air velocity, temperature, moisture, energy balance) of agricultural structures.
