Research Interests and Expertise

Primary Research Theme: Aerodynamics and Fluid Mechanics
Secondary Research Theme: Aeroelasticity, Fluid-Structure Interaction and Flow-Induced Vibrations

• Aerodynamics of airfoils, wings and aeronautical configurations in subsonic, transonic and supersonic flows.
• Unsteady aerodynamics of oscillating airfoils and wings in incompressible and compressible flows.
• Aerodynamics of airfoils and wings at low Reynolds numbers for unmanned and micro-aerial vehicles.
• Study of aerodynamic problems of unspecified geometry: adaptive and flexible airfoils and wings, jet flaps, compliant surfaces, nozzle design.
• Development of numerical methods for aerodynamic problems based on finite volume, finite difference and hybrid spectral formulations and Lagrangian methods.
• Study of aerodynamic interaction problems (ground effect, wing-tail interaction, wind tunnel wall effect).
• Study of unsteady confined flows with oscillating boundaries and variable inflow velocity.
• Steady and unsteady fluid-structure interaction and dynamics of structures subjected to unsteady flows.
• Aeroelastic oscillations of structures (use of piezoelectric actuators and sensors to prevent structural instabilities and to detect cracks in the structure).
• Atmospheric flight for space missions and aero-gravity assist.
