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.
Continuous adjoint formulations for the optimal shape design of rotor blades 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.
A coupled-adjoint technique enabling aeroacoustic shape design has also been demonstrated. The method
is general and could be applied to other multiphysics problems where adjoint sensitivites are desired.
Ongoing work seeks to extend the present aerodynamic+aeroacoustic analysis and design methodologies
to large-scale unsteady applications, such as counter-rotating open rotors. All numerical implementation
has been performed within the open source SU2 software suite.
