Profile
Dr. Vasel-Be-Hagh joined TN Tech’s Mechanical Engineering Department in Fall 2017. He is the founder and principle investigator of the Fluid Mechanics Research Laboratory. His research interests include fluids mechanics, heat transfer, and thermodynamics for engineering applications, particularly energy conversion and storage technologies.


Current Research Assistants / Students

Madison Dittner
M.Sc. Student (Summer 2018 – present)
E: medittner42@students.tntech.edu 
Madison’s research is focused on developing a numerical platform for geometry optimization. Madison has 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.


Cody Long
M.Sc. Student (Fall 2018 – present)
E: cslong42@students.tntech.edu 
Cody studies flow over a finite, buoyant, flexible cylinder that is free to oscillate within the turbulent boundary layer of a solid bed. Cody’s research, which is based on computational fluid dynamics, is crucial for many engineering applications, including design and development of a specific offshore power-generating energy storage. We have come up with a pretty easy, but effective strategy for developing two-way fluid-structure simulations where the structure (a cylinder in Cody’s research) freely responds to the flow.


Ryan Nash
M.Sc. Student (Fall 2018 – present)
E: rrnash42@students.tntech.edu 
Ryan develops technologies to steer wake of wind turbines in order to improve performance of utility-scale wind farms as a whole. Ryan designed, fabricated, and programmed the fully automated, 3D traverse system that is currently being used at the research wind tunnel. He greatly contributed to design and fabrication of the rest of the the wind tunnel too. Ryan uses our research wind tunnel to conduct his research.
