Daniel Johnson
Daniel Johnson started working on his Ph.D. in January 2023 and has joined the C-PARC group. He will use experimental and theoretical modeling to research high-swirled premixed hydrogen/air flame stabilization mechanisms. Daniel received his Bachelor’s and Master of Science degrees in Aerospace Engineering from the University of Tennessee in Knoxville. As an undergraduate, his senior design focus was orbital determination and propulsion systems. He presented his research, Mission Opportunities to Trans-Neptunian Objects – Part VI, at the 2019 Astrodynamics Specialist Conference in Portland, Maine. His Master’s studies focused on fluid dynamics, numerical analysis, modeling and design. After graduating in 2021, he accepted a position with a government contractor for the Space Force in Dahlgren, Virginia, where he worked for a year as an orbital analyst solving various operational orbital mechanics problems and processing data for orbit states and predictions to enable customer situational awareness in orbital analysis, space defense, and satellite collision avoidance. Daniel is originally from Middle Tennessee. In his spare time, he enjoys reading and spending time outdoors on hikes, camping, and scuba diving.
Joshua McBeth
Josh McBeth is a current undergraduate student at Embry Riddle Aeronautical University studying aerospace engineering with a minor in propulsion; who spent the summer of 2022 at UTSI working at C-PARC. His research is focused on the development of a H2/O2 flame by conducting simulations, gathering data and generating an operating performance map to establish viable operating conditions in order to provide baseline setting for heat exchanger design. After his internship he will head back to complete his degree while continuing his research under the guidance of Dr. Palies. Once he graduates, he wants to pursue a PhD focusing his research on propulsion. Outside of school, Josh loves to play soccer, spending time with friends and family and gaming.
Darrick Minshall
Darrick Minshall is a Mechanical Engineering major at the University of Utah. Darrick has always been fascinated by aerospace engineering, and often pestered his teachers in elementary school by flying paper airplanes in class. By studying mechanical design, his interest in airplanes developed into the goal of one day working in an environment where he could explore new ideas for aviation. Darrick’s internship with C-PARC at the University of Tennessee Space Institute has expanded upon his skills as an engineer by providing relevant to topics to study, giving him opportunities to generate never-before-seen ideas, and teaching him how to test his ideas in computer-based simulations. Darrick’s time at UTSI has improved his abilities as an engineer and he looks forward to applying what he’s learned in a professional career.
Tate Prater
Tate Prater is a first-year graduate student from Chattanooga, Tennessee. In the spring of 2021, he graduated from the University of Tennessee, Knoxville with a bachelor’s degree in aerospace engineering. His current role at the C-PARC group at UTSI includes one-dimensional flame simulations using the Cantera software as well as the study of fuel and air mixing-mechanisms to enable future lean, fully premixed combustion for gas turbine engines. I am grateful and excited to be a part of the C-PARC team where we have the opportunity to work towards clean aviation by greatly reducing the amounts of carbon dioxide and nitrous oxide emitted into the atmosphere. Outside of school, Tate enjoys playing sports, spending time with friends and family, and private piloting.
Gan Xiao
The increase of computing power -over time has rapidly expanded the roles of DNS as an essential tool to provide insights into the intricate dynamics of the turbulence-chemistry interaction with emphasis on more complexity associated with real fuel effects chemistry and operating conditions approaching those realized in the realistic combustion systems. Nonetheless, the emphasis on realistic geometry has yet to be tackled as most configurations investigated focused on 3D DNS boxes with the periodic domain. My current work discusses a reacting fluid dynamic DNS simulation of a premixed H2/air swirling flame under high swirl atmospheric conditions and develop a computational strategy to compute at DNS resolutions a relevant high-swirl geometrical configuration by including the swirler part itself and solving two of the key flame and turbulence interaction physical scales. Gan Xiao likes running, driving, and cooking in my spare time, and enjoy the life at Tullahoma.
