报告人简介:Dr. San Andrés is a qualified analyst and experimentalist in the fields of fluid film lubrication and rotordynamics. He directs a laboratory with an average of seven fully supported research assistants per year. Dr. San Andrés 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 gas bearings. Dr. San Andrés 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 of hybrid thrust bearings and two-phase fluid seals for submersible (subsea) TM, and high speed gas face seals and bearings with enhanced damping characteristics.
The Tribology Group has developed advanced and efficient computational models for the analysis and design of process-fluid film bearings (hydrostatic and hydrodynamic), gas bearings including foil bearings, gas damper and labyrinth seals, tilting pad bearings and squeeze film dampers. The thermo hydrodynamic flow models account for fluid inertia and variable properties, flow turbulence in exotic bearing geometries. Applications to high-speed turbomachinery include cryogenic turbopumps, aircraft jet engines, industrial compressors, etc. Users include Boeing-Rocketdyne, Pratt & Whitney, NASA Research Centers and Contractors, Philips Laboratory - USAF, TAMU Turbomachinery Research Consortium members, Sulzer-Bingham, GE Aircraft Engines Group, SNECMA-SEP-France, Hamilton Std., Siemens, Capstone Micro Turbines, and educational institutions.
