I joined TN Tech’s Mechanical Engineering Department in Fall 2017 and founded the Fluid Mechanics Research Laboratory! My research interests include fluids mechanics, heat transfer, and thermodynamics for engineering applications, particularly energy conversion and storage technologies. Please feel free to reach out to me at avaselbehagh@tntech.edu if you have any questions or are interested in working with FMRL.

I would like to recognize and thank my great assistants, current and former, for helping me develop this research laboratory. Below, you can learn more about them!

Ty Hagan
Ph.D. Student (Summer 2021 – present)
E: tahagan42@tntech.edu
Ty assists FMRL with designing and fabricating an experimental setup for studying thermodynamics, heat transfer, and fluid mechanics of a condenser. Prior to joining graduate school, Ty used to work at FMRL as an undergraduate research assistant. Ty is very skilled in CAD, design and fabrication, and experimental research. .

Trevor (Daniel) Cannon
Ph.D. Student (Fall 2020 – present)
E: dtcannon42@tntech.edu 
Trevor investigates atmospheric flows using computational fluid dynamics. He conducts large-eddy simulations using SOFWA and OpenFOAM on TN Tech’s high-performance computing cluster. He is very good at using high-performance computing clusters. Trevor is also working on designing, fabricating, and instrumenting an experimental setup to obtain field data. He requires such data to feed his models’ boundary conditions and validate his computational results.

Reza Nouri
PhD Student (Spring 2019 – present)
E: rnouri42@tntech.edu
Reza studies the aerodynamics of wind farms using Large Eddy Simulations. His research is mainly concerned with controlling the direction and strength of wind turbine wakes. Reza conducts these simulations via SOWFA (Simulator fOr Wind Farm Applications), a CFD solver developed by NREL.

PhD Student (Summer 2018 – present)
E: kuchemegrad@me.com
Doug is pursuing his Ph.D. degree while holding a full-time position as an R&D staff member at Oak Ridge National Laboratory (ORNL). Doug’s research is concerned with the characterization of Uranium aerosols. He is almost done with his Ph.D. dissertation and is getting ready to defend it! .

Michael Hackler
M.Sc. Student (Fall 2020 – present)
E: mrhackler42@tntech.edu 
Michael research is focused on improving the technology readiness level of a harvesting/storage device, called SAVER. SAVER stands for storage integrated vortex hydro-kinetic energy converter.



Yang Zhao
M.Sc. Student (Spring 2020 – present)
E: yzhao42@tntech.edu
Yang  is researching whether adding control surfaces to the blades causes the individual efficiency of wind turbines to improve, or their aerodynamic interactions with their downstream counterparts to decrease..




William Taylor McCarty
Research Assistant (Spring 2021 – present)
E: wtmccarty42@tntech.edu
Taylor assists FMRL with modeling thermal processes using ANSYS..



Benjamin Cooper
Research Assistant (Summer 2018 and Summer 2021 – present)
E: bjcooper43@tntech.edu
Ben assists FMRL with designing and fabricating a wind turbine setup that provides torque control. Ben worked with us back in 2018 too. He helped us manufacture the three-dimensional traverse that we currently use at the wind tunnel unit. .



Former Research Assistants / Students

Madison Dittner
M.Sc. Student (Summer 2018 – Spring 2020)
Current: The United States Patent and Trademark Office
E: medittner42@tntech.edu 
Madison’s research was focused on developing a numerical platform for geometry optimization. Madison developed a Genetic Algorithm that employs two commercial software packages (ANSYS and Solidworks). The GA model assigns values to the parameters that are used to characterize the geometry of interest. Solidworks makes the geometry and forwards it to ANSYS. Fluent module of ANSYS develops a CFD simulation for the new geometry and forwards results of interest back to the GA model. GA uses the simulation results to modify the geometric parameters. This continues until the optimal geometry is research. Madison uses TN Tech’s high-performance computing cluster to conduct CFD simulations.

Madison successfully defended her thesis in Spring 2020! Her thesis can be accessed here
