 10:00-11:30 Prof. Dara W. Childs (Texas A&M University, USA)
| "Liquid and Gas Annular Seals and Their Impact on Rotordynamics” |
 |
:: Biography ::
Dr. Dara W. Childs is the Leland T. Jordan Professor of Mechanical Engineering at Texas A&M University. He has authored numerous technical papers on rotordynamics plus the book, Turbomachinery Rotordynamics: Phenomena, Modeling, and Analysis. He has been director of the Turbomachinery Laboratory at Texas A&M since 1984. |

13:00-15:00 Prof. Luis San Andrés (Texas A&M University, USA)
| "Gas Bearings for Microturbomachinery Rotordynamic Performance & Stability" |
 |
:: Biography ::
Dr. San Andres has an international reputation as a qualified analyst and experimentalist in the fields of fluid film lubrication and rotordynamics. Dr. San Andres has provided major advances to the technology of hybrid bearings (hydrostatic / hydrodynamic) for applications in primary power space turbopumps. The bearings investigated, both theoretically and experimentally, include flexure-pivot tilting pad bearings, angled injection hybrid bearings and foil-bearings. Current research interests include analysis and experimental verification of gas foil bearing performance for high temperature oil free turbomachinery and squeeze film dampers for aircraft jet engines. The research will enable a green revolution in personal transportation.
Dr. San Andres has managed research projects with a value exceeding 6.2M US dollars. He directs a laboratory with an average of seven fully supported research assistants each year. Dr. San Andres has educated many graduate students currently practicing their skills and providing services and leadership to turbomachinery manufacturers. Dr. San Andres and his students have published extensively in the archival literature: 125 peer reviewed papers, 47+39 reviewed and invited conference papers, 100+ technical reports. Dr. San Andres also holds five patents and the copyright for various computational programs predicting the performance of liquid and gas hydrostatic and hydrodynamic bearings, seals, and foil bearings. |

15:30-17:30 Prof. Hiroshi Kanki (Kobe Univ., Japan)
| "Industrial case studies on turbomachinery vibration problems and solutions" |
 |
:: Biography ::
Dr.Kanki received M.S degree of Mechanical Engineering from Kobe University in 1970
,and received his PhD degree from Osaka University in 1977. He worked as a research engineer of rotor dynamics and manager of Vibration and Noise Control Laboratory of Takasago R&D Center of Mitsubishi Heavy Industries from 1970 to 1995. He worked as professor of Mechanical Engineering Department of Kobe University from 1995 to 2009.
After retiring Kobe University ,He is emeritus professor of Kobe University, and working as vice president of Gyrodynamics Ltd and technical adviser of Takasago Machinery Works of Mitsubishi Heavy Industries. His contributions for rotor dynamics are Balancing area: Modal circle balancing method and L.M.I computer aided balancing system development. Rotor system design area: New critical speed criteria using Q-factor.
Rotor stability area: Stability improvement of high pressure centrifugal compressor and research of steam whirl of high pressure turbine with partial admission operation.
And much contribution for ISO vibration standards. Recent his work are development of New Wave Power Generation System using Gyroscopic Moment, and education of professional engineers.
