Presenters: Nathan F. Andrews, Group Leader, Southwest Research Institute & Dr. Carl Popelar, Staff Engineer, Southwest Research Institute
Dr. Carl Popelar is a Staff Engineer in the Materials Engineering Department at Southwest Research Institute. His primary area of interest focuses on characterizing the mechanical behavior of materials in order to predict their in situ performance. He has a broad background in mechanical characterization and modeling of materials including metals, polymers, composites and tissues, with more than 25 years of experience in characterizing and modeling material behavior for structural integrity and reliability assessments. Dr. Popelar manages the metals AM facility at SwRI and leads activities related quantifying the effect of process and presence of defect on the performance of high-consequence AM components.
Mr. Nathan Andrews is a Group Leader in the Machinery Department at Southwest Research Institute. His areas of focus are currently geared toward liquid propulsion systems, with research interests and experience in thermal/fluid sciences, computational fluid dynamics (CFD) and other numerical modeling. He is also active in researching and developing additive manufacturing (AM) applications, and is also experienced in general mechanical design, testing, manufacturing specification. Specifically, his research includes modeling of liquid fueled space launch vehicle pressurization systems (using Thermal Desktop - Sinda/Fluint), combustion and CFD analyses in supercritical CO2 turbine power cycles, and heat transfer analyses for aircraft manufacturing applications. He is involved in actively exploring applications for AM to make or support turbomachinery components. He also has experience with fluid and thermal property calculations of oil and gas systems.
