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
the editor 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.
