Turbo Lab Co-authors receive ASME Best Paper Award
Dr. Luis San Andrés and two former students in the Turbomachinery Laboratory at Texas A&M have received a 2018 Best Paper Award from the American Society of Mechanical Engineers (ASME) Structures and Dynamics Committee.
Dr. Luis San Andrés, Mast-Childs Chair professor in the Department of Mechanical Engineering, Mr. Bonjin Koo, and Dr. Sunghwa Jeung, former students in the Turbo Lab, were recognized for their paper, “Experimental Force Coefficients for Two Sealed Ends Squeeze Film Dampers (Piston Rings and O-rings): An Assessment of Their Similarities and Differences.” The trio presented the paper at the 2018 Turbomachinery Technical Conference & Exposition (Turbo Expo) in Lillestrøm, Norway, and will receive the award at the 2019 Turbo Expo in Phoenix, Arizona, June 17-22.
The purpose of the multiple year research, sponsored by Pratt & Whitney, was to quantify for the first time the performance of a squeeze film damper (SFD) implementing two commonly used end seals, piston rings (PRs) and O-rings (ORs). No prior art compares the performance of a PR-SFD vis-à-vis that of an OR-SFD. Supplying lubricant with a large enough pressure (flow rate) is crucial to avoid the pervasiveness of air ingestion that reduces damping capacity.
The Best Paper Award is an opportunity to recognize outstanding technical papers, to acknowledge the authors’ contribution to the gas turbine industry, and to support and maintain the high quality of papers presented.
“The co-authors are two outstanding former students presently making waves in industry,” San Andrés said. Koo is a Product Development Engineer with Daikin Applied in the Application Development Center, and Jeung is employed with Ingersoll Rand as a Senior Compressor Design Engineer in Compressor Technology and Development.
The ASME Turbo Expo Technical Conference announced the 2018 Turbo Expo Best Papers will be published in an open access digital publication. The honor marks the first time the Turbo Expo Best Papers publication will be offered in an open access digital format. The co-authors’ paper will appear in the publication.
The Texas A&M Engineering Experiment Station (TEES) Turbomachinery Laboratory makes a vital impact on turbomachinery and related industries through research, education and professional workforce development.
