About
Ramis Örlü is an associate professor in fluid mechanics at the Department of Mechanical, Electrical and Chemical Engineering at OsloMet – Oslo Metropolitan University, adjunct professor at the University of Bologna, Italy (www.unibo.it/sitoweb/ramis.orlu2/en), and researcher/docent at KTH Royal Institute of Technology, Sweden (www.kth.se/profile/orlu). Between 2020-2023 he was a Mercator Fellow at the Karlsruhe Institute of Technology (KIT), Germany.
He completed an engineering degree (Dipl. Ing.) in Germany at the Ruhr University Bochum in applied mechanics (2003) and a Ph.D. in engineering mechanics in the field of fluid dynamics (2009) at KTH Royal Institute of Technology (Sweden), where he also became docent in experimental fluid physics (2015). Ramis has conducted research on fundamental and industrial turbulent flows, focusing on smooth and rough wall-bounded flows and their control related to skin-friction and drag reduction by means of passive and active techniques involving large-scale wind tunnel facilities and state-of-the-art measurement techniques.
He serves as the organizer of the iTi (interdisciplinary Turbulence initiative) Conference on Turbulence, an Editor of the Progress in Turbulence book series in Springer, an Editor of Experimental Thermal and Fluid Science, a member of the Editorial Advisory Board of Flow, Turbulence and Combustion and Editorial Board member of Advances in Aerodynamics, besides acting as Guest Editor and Scientific Council member of international Centres and Conferences.
