  • Hydroelasticity of Rigid and Flexible Surface Piercing Hydrofoils

    Experimental studies of rigid and flexible surface-piercing struts in multi-phase flows.

    Control room of CNR INSEAN Flow Channel

    Surface piercing lifting-bodies, such as hydrofoils, propellers, and control surfaces, are prone to ventilation, cavitation, or a combination of both. Multi-phase and multi-component flows can dramatically reduce the ability of marine systems to perform as intended, and the physics underpinning ventilation are poorly understood.


    Additionally, the interaction of hydrodynamics and structural motions possesses a number of challenges not present in classic aeroelastic analyses, including larger viscous effects, multiple phases, and the presence of a free surface.

    The objectives of this research are

    1.  To characterize the hydrodynamic flow regimes and stability of multi-phase flows on surface-piercing hydrofoils.
    2.  To examine the fluid-structure interactions of flexible lifting surfaces in multi-phase flow.
    3.  To execute a pioneering experimental study with new methods and instrumentation, useful for future FSI research.
  • Modeling and Computational Work

    My work in physics-based and reduced-order modeling of physical systems.

    Low-fidelity models can fill a critical gap between costly high-fidelity simulations and purely empirical regressions. I have worked to develop physics-based models that provide reasonable levels of accuracy with minimal computational cost. Semi-theoretical modeling has applications in active control, structural health monitoring, indirect sensing, and informational readouts to pilots/operators.

  • Sensor Development

    Design and testing of low-cost, robust shape-sensing for deformable marine/aerospace structures

    Technologies commonly used to measure the deformations of flexible marine and aerospace structures include accelerometry, gyroscopy, and optical methods (laser vibrometry, digital image correlation, etc… ). These approaches, while useful, do not enable reliable measurements of static and dynamic motions where optical access is limited or where the sensors are not mounted rigidly — as may occur during tests outside of a controlled laboratory setting. Moreover, the sophistication and large expense of optics-based systems discourages their use in harsh environments.


    It is the objective of this project to develop a complementary sensor for use in marine, aerospace, and other fields where the static and dynamic deformations of flexible and slender structures must be measured. Using classical theory and inexpensive strain gauges, we have achieved accuracy that matches or exceeds current sensing solutions across an unlimited frequency bandwidth, is field-repairable, runs in real-time, and costs less than 5% the cost of optics-based systems.
