Dr. Keun Ryu

Associate Professor Department of Mechanical Engineering and Director of the Turbomachinery Laboratory, Hanyang University, South Korea

Dr. Keun Ryu is an Associate Professor in the Department of Mechanical Engineering and Director of the Turbomachinery Laboratory at Hanyang University in South Korea. He received B.S. (2003) and M.S. (2005) degrees (Mechanical Engineering) from Hanyang University in Seoul, South Korea as well as M.S (2007) and Ph.D (2011) degrees (Mechanical Engineering) from Texas A&M University.

Prior to joining Hanyang University (2013), Dr. Ryu worked at the Korea Institute of Science and Technology (Seoul, South Korea) as a Graduated Studying Fellow (2003−2004), the Turbomachinery Laboratory at Texas A&M University (College Station, Texas, USA) as a Graduate Research Assistant (2005−2010), and BorgWarner Turbo Systems (Arden, North Carolina, USA) as a Senior Development Engineer (2010−2013).

Dr. Ryu is a highly experienced analyst and experimentalist in the fields of high speed bearings and rotordynamics, having earned an outstanding international reputation because of his enduring experimental and analytical research program on rotating machinery. He has produced significant progress in the analysis and experimental parameter identification of gas bearings for oil-free turbomachinery. Over the last fifteen years, his research has greatly advanced the gas bearing technology with immediate applicability in high speed turbomachinery industry. In 2016, he initiated a research program to advance the technology of rotor systems supported on hybrid cryogenic bearings for reusable liquid rocket engine turbopumps. His current research quantifies the effect of bearing configurations on the rotordynamic performance of a hybrid bearing supported rotor system.

Dr. Ryu has presented and published more than 100 technical articles and reports on fluid film bearings and rotordynamics. He also holds more than ten patents for automotive turbochargers, micro gas turbines, rocket engine turbopumps, fluid film bearings, and dampers. ASME (American Society of Mechanical Engineers) and STLE (Society of Tribologists and Lubrication Engineers) have recognized his outstanding contributions to advanced gas bearing technology with various awards.

Dr. Ryu is the current Technical Program Chair of ASME Turbo Expo 2022, the former Vice Review Chair of ASME Turbo Expo (2019-2021), the former Vanguard Chair of the ASME IGTI Structures & Dynamics Committee (2015-2019), and the former Chair of the ASME IGTI Microturbines, Turbochargers & Small Turbomachines Committee (2017-2019). He is also the Associate Editor of STLE Tribology Transactions and the Editor of Tribology and Lubricants (the Journal of Korean Tribology Society).
