About
Ramis Örlü obtained an engineering degree (Dipl.-Ing.) in mechanical engineering from Ruhr University Bochum, Germany, in 2003, followed by a Ph.D. in engineering mechanics with a focus on experimental fluid dynamics and turbulence at KTH Royal Institute of Technology, Sweden, in 2009. In 2015, he was appointed docent in experimental fluid physics at KTH and has held an adjunct professorship at the University of Bologna since 2017. In 2023, he joined OsloMet – Oslo Metropolitan University, Norway, as an associate professor in fluid mechanics and became a full professor at the same institution in 2024. Over the years, he has held fellowships and guest professorships at Karlsruhe Institute of Technology (KIT), Germany; Friedrich-Alexander-Universität (FAU) Erlangen, Germany; and the Turkish-German University in Istanbul, Turkey.
His research is centered on both fundamental and industrial aspects of turbulent flows, with an emphasis on skin-friction and drag reduction through passive and active control techniques. He has extensive experience using large-scale wind tunnel facilities and advanced measurement methods, as well as close interactions with high-fidelity simulations to cross-validate experiments and simulations. He is also Editor-in-Cief of Experimental Thermal and Fluid Science, a member of the Editorial Advisory Board for Flow, Turbulence and Combustion and Advances in Aerodynamics, and serves as a co-editor of the Progress in Turbulence series.
