PROFESSIONAL EXPERIENCE
SEAGATE TECHNOLOGY, LLC, Longmont, CO 2013-Present
Thermal Mechanical Engineer (Senior Staff)
Thermally analyzed and tested both 2.5 inch and M.2 form factor SSDs (solid state drives) to validate that all active components (NANDs, SoCs, voltage regulators, etc.) maintained their respective temperature limits and to determine the minimum amount of cooling required for ASHRAE environments.
Investigated, developed and acquired the needed test hardware to be able to do flow and thermal testing of both SSDs and HDDs as well as expanders, PCBs, JBODs, fans, and heat sinks, along with entire data center enclosures. The hardware included an airflow chamber, multi-meters, data-loggers, and necessary thermocouples and anemometers.
Using FEA structural models, found that one of the HDD enclosures that was being developed was not sufficiently stiff to withstand the weight of the HDDs and other electrical hardware and was able to work with the team to improve the enclosure's stiffness.
Created thermal and flow assessments (both 1D simple models using MacroFlow and spreadsheets, as well as in-depth 3D CFD using ANSYS Icepak) of systems and components from the conceptual to the detailed design phases and validated these analytical models through flow and thermal testing once the systems were available.
Worked with internal experts to ensure system level EMI/RFI compliance & to develop enclosure fixtures for shock/vibration testing.
INFINIA CORPORATION, Ogden, UT 2011-2013
Senior Analytical Engineer
Developed a liquid-cooled, cold plate, design and thermal interface lay-up to dissipate the heat generated by a high voltage PCB that met the company's economic goal and increased the thermal dissipation potential by more than double. This work also entailed evaluating the size of an air -cooled parallel plate fin heat sink.
Participated in the temperature and fluid flow measurement of a liquid cooled high voltage PCB to validate and verify the generated thermal models and hand calculations.
Installed and became familiar with the free OpenFOAM CFD analysis package to economically increase the analysis capabilities of the company. Created a 3D model to validate test results of a combustion heat exchanger.
Led the mechanical design, analysis, and construction of a reverse cycle Stirling engine that entailed structural analysis of the pressure vessel, vibration and fluid flow analyses, and developing drawings using GD&T.
ATK LAUNCH SYSTEMS INC, Promontory, UT 2005-2011
Senior Thermal/Aero Engineer & Ares I First Stage Heat Transfer Lead
As lead - Coordinated the heat transfer work for the Ares First Stage. Organized the documentation of the analyses and was responsible for maintaining a plan to show that all NASA requirements and design specifications were met. Participated in design reviews of all technical work as well as related documentation prior to NASA submittal.
Ran 1D, 2D, and 3D thermal models (including mass flow, convection, conduction, and radiation) for various components of solid rocket motors and other hardware and assessed necessary thermal protection systems to keep those components/locations below their respective temperature limits.
Helped create a new conjugate thermal analysis methodology to assess the nozzle joints that combined CFD quasi-steady state results, phenolic swelling, off-gassing, and circumferential pressure differential effects.
Initiated modifications and fixes to an in-house conjugate (coupled 1D CFD and 2D/3D SINDA/G) code to include effects of high speed gas flow and implemented changes to the impingement heat transfer coefficient correlations.
PRATT & WHITNEY, East Hartford, CT 1998-2005
Senior Thermal/Aero Engineer
Used ANSYS, Fluent (CFD), and other in-house codes to run heat transfer and fluid flow analyses of both static and rotating components in gas turbine engines.
Used Fluent to help in inventing a modification to a rotating component that reduces the extremely high heat transfer coefficients it was encountering – Patent received.
