Current Research Focus

Development of new high-fidelity, multidisciplinary design methodologies for efficient, quiet rotors that meet next generation propulsion and energy challenges: open rotors, propellers, helicopter rotors, turbomachinery, and wind turbines.





Recent Work

My research focuses on the development of new design methodologies for aerospace systems, including high-fidelity, adjoint-based techniques for optimal shape design, as well as tools for design at the conceptual level. These new methodologies will enable the design of next generation aerospace vehicles with greatly reduced fuel burn, emissions, and noise. Of particular interest are rotating applications for meeting future propulsion and energy challenges: open rotors, propellers, helicopter rotors, turbomachinery, and wind turbines.

Continuous adjoint formulations for the optimal shape design of rotating and other unsteady systems have been developed and implemented. Capabilities include design for both steady problems in a rotating reference frame and unsteady problems via a time-accurate adjoint.

Current work extends the present aerodynamic analysis and design methodologies to large-scale, viscous, unsteady applications on dynamic meshes. All numerical implementation has been performed within the open-source SU2 software suite.
