Harnessing fluid-structure interaction for robust aerodynamic performance

We are interested in canonical studies of the role of flexibility and active surface morphing on wing performance, particularly in the presence of unsteady maneuvers and gusts. Physical insights from these investigations can inform future designs of microair- and unmanned aerial vehicles that harness fluid-structure interplay for improved maneuverability and robustness to gusts and other disturbances.

 

Understanding flow physics towards improved bio-inspired propulsors

In locomotion of small engineered craft, paradigm shifts in which fixed-wing propulsion is replaced with bio-inspired strategies (e.g., flapping) are increasingly being investigated by the scientific community. To complement these efforts, we are interested in performing fundamental studies on the role of flexibility and unsteady kinematics in these nontraditional locomotive strategies.

 

Utilizing fluid-structure interaction for renewable energy harvesting

Structures immersed in fluid can be set into vibration under certain combinations of flow conditions and structural parameters. This motion can be converted to electricity using, e.g., piezoelectric devices. Previous studies of these systems have focused predominantly on uniform structural properties and single devices. Our aim is to investigate the role of nonuniform structural properties and multiple devices on energy harvesting potential.

 

Numerical method development

We are interested in developing robust and efficient computational tools for simulating and analyzing fluid-structure interaction systems. Projects of interest include improved time stepping algorithms and code performance of our nonlinear simulation package, and developments to data analysis techniques for elucidating the physics of fluid-structure mechanisms.
