Dr. San Andrés is a student advisor for the
TEES Undergraduate Summer Research Program since 1992. He also volunteers work
since 1996 for the Science, Technology & Youth Symposium (high school
students) and the Science and Engineering Workshop for High School Teachers.
The responsibilities as a mentor to a
minority student include academic guidance, addressing cultural issues, helping
with administrative paperwork, and offering moral encouragement.
In 2001, Dr. San Andrés established an
exchange program with undergraduate students from Universidad Simon Bolivar (
Dr. San Andrés also sponsors the work and
training of undergraduate students in his laboratory. Four to six students per
year assist to graduate students in their research work.

The Texas
A&M University System through its Technology Licensing Office holds
copyrights for the computational programs developed by Dr. Luis San Andrés for
NASA and its contractors. The programs predict the static and dynamic force
performance for the following fluid film bearings and seal types:
2Dhydropad© gas
hydrodynamic/hydrostatic rigid bearings
Dseal© gas
labyrinth and gas pocket damper seals
Hydrosealt© hydrostatic/hydrodynamic radial bearings and annular seals
Hydroflext© + tilting and flexure pivot journal bearings, foil bearings,
Hydrotran© + transient analysis for blade loss and g-load simulations,
Hydrojet© + angled injection hydrostatic bearings.
Hseal2p© two-phase flow cryogenic fluid annular seals.
Hydrothrust© hydrostatci/hydrodynamic thrust bearings and inner pressurized
face seals.
The
programs running on PCs include full fluid inertia, turbulence flow and thermohydrodynamic
models for high-speed, high-pressure, hot/cold cryogenic and process fluid
operating conditions. The computational programs have been validated with
extensive experimental measurements performed at TAMU and elsewhere. The codes
built in Fortran F90 are extremely fast and user friendly.
These
programs and the experimental validation have allowed the success and
implementation of an all-fluid film bearing technology for advanced rocket engine
turbopumps. Full descriptions of the programs, options for calculations and
system requirements are given at the following URL address: http://metrib.tamu.edu/rotorlab.htm
under the software heading.

Since
1990 Dr. Luis San Andrés has developed a number of computational programs for
the Turbomachinery Research Consortium (TRC). Some of these programs have been
recently integrated to the XLtrc© rotordynamics
analysis suite of programs developed exclusively for the TRC members. XLtrc© performs complete rotordynamic
analysis (stability and imbalance response) of rotors supported in fluid film
bearing elements, seals, ball bearings, etc. Dr. San Andrés codes predict the
steady state rotor eccentricity and rotordynamic force coefficients as a
function of the operating conditions (rotational speed and load) for the
following types of bearing and seal configurations:
XLlanseal© annular pressure
seals (laminar and turbulent flow, variable fluid properties),
XLhydpad© laminar flow
hydrostatic/hydrodynamic radial bearings of arbitrary geometry,
XLlsfd© laminar
flow squeeze film dampers with end seals, circular centered orbits,
XLlubgt© floating
ring multiple-groove seals (laminar flow and thermal effects),
XLosfd© laminar
flow open end squeeze film dampers, arbitrary static eccentricity,
XLpresdm© laminar flow
pressure dam and multiple-lobe journal bearings,
XLsfdfem© laminar flow open/sealed
squeeze film dampers with fluid inertia effects,
XLtfpbrg© tilting pad
journal bearings and fixed arc bearings, laminar and turbulent flows, includes a number of thermal models.
In
addition, Dr. San Andrés and students have developed the following
computational programs for the TRC:
JBfish© herringbone
grooved journal bearings and spirally grooved seals (laminar flow).
Spiral©,
Spiralc© flat & spirally
grooved face (noncontacting) seals, incompressible fluid and
ideal
(buffer) gases. Flowserve (Durametallic) is currently evaluating this software
for licensing (04/99).
