OverviewAI-generated summary

D. Keith Walters conducts research focused on fluid dynamics, turbulence modeling, and heat transfer, with a particular emphasis on low-Prandtl number buoyant flows. His work utilizes direct numerical simulations and computational fluid dynamics (CFD) to analyze turbulent flow structures and thermal characteristics. Walters also investigates the performance of various turbulence models, including hybrid RANS-LES approaches, for predicting heat transfer under different flow conditions, such as those involving buoyancy and separated flows.

His research extends to the development of analytical models for phenomena like electromagnetic induction in ferrofluid flows. Walters has also contributed to the creation of small-scale propeller thrust models through experimental and CFD methods. His scholarship metrics include an h-index of 27, with 145 total publications and over 3,146 citations. He has served as PI on a National Science Foundation grant totaling $159,940 for the development of low-order modeling methods for oscillating foil energy harvesting.

Walters collaborates with other faculty members at the University of Arkansas at Fayetteville, including James H. Leylek, Keisha B. Walters, Cole C. Simmonds, and Michael Tullis, on shared publications. He maintains an active laboratory website to disseminate his research.
