Fluid Structure Interactions

I am presently studying fluid-structure interactions in high-speed flows. These simulations are critical in understanding structural behavior of thin panels when subjected to supersonic and hypersonic flows. Fluid-structure interactions can lead to structural deformation and catastrophic failure which makes it critical to understand these interaction phenomena in detail for design studies and consideration.

    Fluid Structure Interactions in Subsonic Flow - Fully Started Conditions

    High fidelity scale-resolved numerical simulations of a thin aluminum panel in Mach 0.50 subsonic flow for fully started conditions of 400 milliseconds. Vortex shedding can be observed below the shear layer.

    Time evolution of a Mach 0.50 flow showing thin aluminum panel oscillations with density and temperature contours, overlaid with velocity streamlines for fully started conditions of 400 milliseconds.

    Fluid Structure Interactions in Supersonic Flows - Initial Transient Conditions

    High fidelity scale-resolved numerical simulations of a thin aluminum panel in Mach 2.11 supersonic flow. These simulations were compared to the experimental results of Bojan, [1], for validation of initial transients.
