Prof. Todd Lowe leads a research team focused on the aeroacoustics and aerodynamics of propulsion inlets and exhausts with advanced capabilities in laser-based optical diagnostics. Fundamentally, his contributions have provided insights for understanding turbulence transport and noise in three-dimensional boundary layers and compressible boundary and shear layers. His instrumentation research has resulted in several notable impacts, including new flow diagnostics with very high spatial and temporal resolution, interpreting particle lag effects on turbulence statistics, flow acceleration measurements, and robust, large field velocimetry for large facilities. Since 2011, he has been the P.I. or co-P.I. on an average $1.25M/year of research contracts and awards from government and industry sponsors including the Office of Naval Research, NASA, US Air Force, Pratt & Whitney, Rolls-Royce, GE and several small businesses. He is co-inventor of two utility patents (nos. 8434723 and 8348553) and has co-authored publications in the areas of laser diagnostics for fluid dynamics, turbulent shear flows, propulsion and power, and signal processing.

Dr. Alexandrina Untaroiu is an Assistant Professor of Mechanical Engineering and Affiliate Faculty in the Department of Biomedical Engineering and Mechanics at Virginia Tech. She received a Ph.D. in Mechanical and Aerospace Engineering and a M.S. in Aerospace Engineering from the University of Virginia. Dr. Untaroiu’s areas of expertise are in computational modeling and fluid-structure interaction. Her research interests include: Turbomachinery, Multiphase Flows, Annular Pressure Seals, Fluid Film Bearings, Rotordynamics, Optimization, and Cardiac-Assist Devices.

Dr. William Copenhaver is currently employed as a Senior Research Engineer for the Mechanical Engineering Department at Virginia Tech performing applied research in compression system distortion tolerance in the TurboLab. He has been involved in compression system research for nearly 38 years at the Air Force Research Laboratory (AFRL). Prior to his retirement from AFRL, in Sept 2017, he served as Senior Advisor on compression systems in the AFRL, Aerospace Systems Directorate, Turbine Engine Division, Turbomachinery Branch. Prior to this assignment he served 9 years as the Turbine Engine Division’s Principal Scientist, leading an in-house team of over 100 government and contractor on-site researchers performing applied research in turbine engine technology. He represented the Air Force in basic and applied compression system research throughout the world, and was requested by many foreign governments to provide seminars on the research efforts underway in compressor aerodynamics. He has made significant contributions in the field of compressor aerodynamics, related to stall in multistage compressors, shock system unsteadiness, blade row interactions and currently inlet/fan interactions and has actively sponsored and participated in university graduate research efforts in the Compressor Aero Research Laboratory. He has been awarded the Air Force Aero Propulsion and Power Laboratory’s (currently the Aerospace Systems Directorate) highest award for in-house research. In addition, Dr. Copenhaver has served on technical committees for AIAA and ASME as well as associate editor for the AIAA Journal of Propulsion and Power, and ASME Journal of Fluids Engineering.  Dr. Copenhaver holds a Bachelors and Master of Science degree from Virginia Tech, and a Ph.D. from Iowa State University; all in Mechanical Engineering.  He is a Fellow of AFRL, AIAA, and ASME.

Dustin Frohnapfel has been a member of the VT TurboLab since 2013. 

Dylan Dawson received his Bachelor’s Degree in Mechanical Engineering with a minor in Physics in 2016 from Virginia Commonwealth University and has been a member of TurboLab since 2016. He is pursuing his Master’s Degree in Mechanical Engineering with focus in StreamVane development for the application of inlet distortion research on turbofan engines. His work in the lab has helped bring Virginia Tech’s newly received TFE731-2 engine to full research capability.

Elizabeth Mack has been working with the TurboLab since 2017. She is finishing up her Masters degree in Engineering Mechanics in the Summer of 2018 and will go on to pursue a PhD in Mechanical Engineering. Her primary focus is on computational fluid dynamics.  She completed her Bachelor’s Degree in Engineering Science and Mechanics in 2015 at Virginia Tech.

TurboLab Alumni

Tamy Guimarães was a member of TurboLab from Fall 2014 to Spring 2018. She is a Mary V. Jones Fellow and CAPES Fellow, and applied laser-based diagnostics, such as Particle Image Velocimetry (PIV) to measure distorted inflows in turbofan engine inlets during her Ph.D. work. She is originally from Brazil, and completer her Bachelor’s Degree in Energy Engineering from Universidade Federal do ABC (UFABC), in Santo André (Brazil) in 2014, after spending a year abroad at University of California, Davis, on a scholarship from the Brazilian government.
