Biography

An internationally acknowledged expert in nonlinear computational aeroelasticity, Prof. Smith joined the School of Aerospace Engineering in 1997. Prior to 1997, she gained experience across a number of aerospace disciplines in industry at the Lockheed-Georgia Company (Now Lockheed-Martin Aerospace Systems), McDonnell-Douglas Helicopter Company and the Georgia Tech Research Institute. Prof. Smith performs computational research in the areas of unsteady aerodynamics and nonlinear aeroelasticity, including CFD-based methods. Her research includes multidisciplinary design incorporating aeroelasticity and acoustic/fluid/structure interactions. She has extensive experience in fixed-wing, space vehicles, rotary-wing and wind energy areas. She has won awards for both research and student mentoring, including a NASA Group Achievement Award for the UH-60A Airloads Workshops and Georgia Tech's Women in Engineering Best Mentor and Faculty awards. She is faculty advisor for the American Helicopter Society student chapter and local Atlanta Chapter President, an AIAA Associate Fellow, and a member of the International Aeroelastic Prediction Workshop organizing committee. She is active in international collaborations with the EU in rotorcraft research. She is a member of the NASA FUN3D development team, and is active in OpenFOAM module development.

Research

Prof. Smith's research includes, but is not limited to advanced numerical methods and engineering analysis associated with unsteady fluid mechanics, applied to the interdisciplinary problems involving aeroelasticity or fluid-structure interaction. Some recent funded research topics include:

  • Unstructured grid methodology development for use in unsteady, multidisciplinary applications
  • Turbulence and transition modeling
  • Overset methods development
  • Multibody dynamic configurations, such as store/ship/vehicle interactions, bluff body aerodynamic-dynamic interactions, wind turbines, and rotorcraft
  • Complex topological analyses, such as configuration-environment impact/interaction
  • Advanced multiresolution, multiscale algorithm development for structured and unstructured grid topological methodologies across Mach regimes
  • Aeroelastic tailoring using microflaps, jets, morphing of wings or rotating blades and design of controls to enhance aeroacoustic and aerodynamic performance in rotorcraft/wind turbines
