experience

Principal Engineer Technology/Innovation  
Baltimore Aircoil Company, June 2012 to September 2013

Key member of R&D team tasked with developing/improving cooling system components, supplied CFD modeling expertise using Star-CCM+ Multiphysics software. Provided planning, design and labor support for R&D testing laboratory. Developed 2-Phase Evaporating Film CFD model for direct contact industrial heat exchanger product improvement initiative. (operating cost reduction) Developed several 1-Phase CFD models for comparative assays on heat exchange and pressure drop performance for line of products in development.

Guest Researcher  
National Institute of Standards and Technology, July 2009 to March 2011

Supported development of National Carbon Emission Measurement Standard to be used for studies on carbon emissions. Worked closely with Building Fire Research Laboratory (BFRL) and Chemical Science and Technology Laboratory (CSTL). Conducted detailed uncertainty analysis of natural gas fueled carbon dioxide source to develop a measurement standard for carbon dioxide measurement equipment. Provided physical and analytical support for duct flow mapping of the Large Fire Laboratory exhaust system to verify that EPA standards were still within reasonable specifications given current technology. Studied and compared databases owned by US Department of Energy (Energy Information Administration) and US Environmental Protection Agency (Emission & Generation Resource Integrated Database) to establish uncertainty of reported carbon emission measurements.

Examination of United States Carbon Dioxide Emission Databases     
Published by (Electric Power Research Institute)
Authors: Paul Borthwick, James Whetstone, Jiann Yang, Antonio Possolo.  Published June 01, 2011

Compares annual carbon dioxide emissions from coal fired steam turbine electric power plants obtained by calculating carbon based on fuel used to carbon dioxide emissions reported from Continious Emission Monitoring methods. Comparision helps to establish levels of uncertainty in US carbon dioxide emissions inventory

Quantification of a Precision Point Source for Generating Carbon Dioxide Emissions     
Published by (Electric Power Research Institute)
Authors: Paul Borthwick, Matt Bundy.  Published June 01, 2011

Examines a large natural gas burner as a precision source for carbon dioxide to be used for testing carbon dioxide emissions measurement techniques on an industrial scale. Paper examines sources of uncertainty and their impact on the final uncertainty of carbon dioxide production. After application of techniques discussed in the paper final uncertainty of the carbon dioxide production is less than +/- 1%

Fuel Injection Spray and Combustion Chamber Wall Impingement in Large Bore Diesel Engines     
Published by (SAE International)
Authors: Paul Borthwick, Patrick V. Farrel.  Published January 01, 2002

Using a visible light laser and optically modified single cylinder Diesel engine this paper covered the findings of fuel injection spray behavior over a range of engine operating conditions. While specific mathematical relationship could not be resolved fuel injection penetration shows an inverse penetration distance as a function of both increasing combustion chamber temperature and density.

Fuel Injection Spray and Combustion Chamber Wall Impingement in Large Bore Industrial Diesel Engines
