Greg S. Harrell, Ph.D., P.E., C.E.M.
BS Mechanical
Engineering, University of Tennessee, Knoxville – 1987
MS Mechanical Engineering-Thermodynamics, University of
Tennessee, Knoxville – 1994
Ph.D. Mechanical
Engineering-Thermodynamics, Virginia Tech (VPI&SU) - 1997
From 1987 to 1993 Dr. Harrell worked as a design engineer and
utilities process
engineer for BASF Corporation at a large industrial
complex. As a utilities process
engineer he had oversight responsibility for the
engineering and technical activities of
the entire utilities department. This included steam
production, electric power
generation, compressed air systems, industrial
refrigeration facilities, industrial HVAC
systems, water filtration facilities and the
wastewater treatment plant.
Dr. Harrell completed his doctoral degree at Virginia Tech (VPI&SU)
with a focuson applied thermodynamics. His major areas of research were
refrigeration cycle
efficiency improvement and two-phase flow. While
completing his doctoral degree he
served as a mechanical engineer for the Energy
Management Institute at Virginia Tech.
From 1997 to 2001 he served as the Director of
Technical Assistance for the institute. In
this capacity Dr. Harrell was directly involved in
various aspects of energy management
for industry located worldwide. These activities
included complete facility energy
analysis, individual process analysis, industrial
training courses, and software
development for energy system modeling. Dr. Harrell
has conducted many energy
surveys for industrial clients throughout the world.
Industrial assessments and training
courses have been completed on six continents in
twenty-two countries and in thirty-six
of the United States.
Along with this work he has conducted many industrial courses on
energy
systems. As a part of this instructional work Dr.
Harrell developed the United States
Department of Energy (USDOE) BestPractices Steam
End-User Training and co-developed
the USDOE Steam Specialist Qualification Training.
He played a major role
in the development of the USDOE BestPractices Steam
Tools and authored the Steam
System Survey Guide, which has become the text for
university mechanical engineering
courses. He has also become a
certified instructor of the Compressed Air Challenge®.
Dr. Harrell served as an Assistant Professor of Mechanical
Engineering at Virginia
Tech, teaching undergraduate and graduate
thermodynamics courses. He served in a
similar position for the Institute for a Secure and
Sustainable Environment (ISSE) of The
University of Tennessee.
Dr. Harrell is also a primary instructor in the North Carolina State University
Energy
Management Diploma Program. Industrial systems
serving as the focus of his attention
are: boilers, steam systems, combined heat and power
systems (cogeneration),
compressed air systems and refrigeration systems.
