Research and development engineer with industrial and academic
experience. Developed test procedures and tested chemical process
design software during development. Taught graduate and undergraduate
classes in chemical process calculation, transport phenomena,
numerical methods, and process control. Developed theoretical
research programs in multi-phase flow and high-performance
computing. Directed pilot plant operation of fluidized bed combustor
for experimental study of plant instrumentation and pollution control.
Modeling and Process Design
- Provided secondary support for customers using PROVISION process
design software. Verified proper usage and program behavior with
developers. Entered verified problems in the project bug log.
- Tested graphical user interface for design of batch distillation
and batch chemical reactors. Verified bug fixes by entering specified
test problems. Entered new bug descriptions and updated existing
entries in the project bug log.
- Developed graduate seminar in system modeling and computer
calculation. Directed seminar research projects in several
areas of process design.
- Analyzed scale-up of dispersed-phase mixing using simulation
models. Showed a mixing rate decrease from 15 to 30 percent
for constant power scale-up.
- Developed FORTRAN models for fluidized bed combustion and sorbent
regeneration. Computed process costs and flowsheets showed economic
viability of fluidized bed burners for an 810 MWatt electric power
Pilot Plant Operation
- Coordinated long-term (100 and 1000 hour) studies in a pilot
plant combustor. Planned installation and operation of experimental
equipment for biology and material science divisions taking part in
the study. Demonstrated a 40 to 60 percent savings in
- Directed studies of hydration of spent limestone at the Grand
Forks Energy Technology Center. Increased limestone conversion by
- Prepared plans for $100,000 upgrade of a unit operations teaching
laboratory. Automated many experiments under this ongoing plan.
Improved analytical instrumentation by adding computer control to
- Specified $100,000 of analytical, control, and data
acquisition equipment for a laboratory fluidized bed pilot plant.
- Evaluated two laser particle size analyzers for on-line analysis
in a fluidized bed pilot plant.
- Directed the installation of an experimental $100,000 laser
Doppler particle size analysis system at the Westinghouse Waltz Mill
facility. Trained two senior engineers and other Westinghouse staff in
Computer Systems Development
- Drafted quality assurance test procedures and carried out testing
of programs for steady state process design (PRO/II), dynamic process
simulation (PROTISS), pipe network flow simulation (NETOPT), and
on-line optimization (ROMeo).
- Developed TCL scripts to automate testing the real time and
electronic data interchange systems of the ROMeo on-line modeling
- Developed TCL and AWK scripts for maintaining the AIM process data
historian for real time testing of the ROMeo on-line modeling system.
- Tested integration of the OTISS dynamic simulator with the steady
state PROVISION process design software. Verified translations of
problems with samples provided by the engineers from the technology
partner developing the dynamic simulator.
- Verified test problems on the client/server version of PRO/II
with PROVISION. Tested Hewlett-Packard, Sun, and IBM RS6000 versions
of the PRO/II calculation server with the PROVISION client running
under Windows 3.11.
- Tested the integration of the graphical user interface with
the NETOPT and PipePhase fluid flow programs for the design of
multi-phase fluid flow piping networks.
- Developed hardware and software specifications for a $25,000
undergraduate IBM PC laboratory. Introduced personal
computers to the curriculum.
- Specified a $20,000 upgrade plan for office computing. Replaced
the office word processor with IBM PC's providing word processing for
- Coordinated campus computing center installation of department
node on campus network. Planned network access for offices and
- Updated AWK scripts for regression analysis to enhance
portability of testing tools between Unix, DOS, Windows 95,
and Windows NT.
- Completed recent training in C programming for the Unix
system with an introduction to device drivers and kernel level
- Presented seminars at the University of Nebraska Mathematics
Department demonstrating vector and parallel algorithms suited to the
Cyber 205, Cray X-MP, and IBM 3090 supercomputers.
- Developed computer models and data acquisition systems using
FORTRAN and PL/1. Skilled with other programming languages
including BASIC, ALGOL, COBOL, Pascal, C/C++, and FORTH.
- Optimized models on various computer systems
including IBM Mainframes (CMS and MVS), Digital Equipment VAX and PDP-10,
Control Data Cyber (NOS), Cray X-MP (CTSS), Unix, and IBM PCs.
- Extended FORTRAN and PL/1 programs for data acquisition in
a fluidized bed pilot plant.
