Nek Sharan, assistant professor in the Department of Aerospace Engineering, seeks to understand how 3D geometries vibrate when exposed to fluid flows.<\/span><\/p>\n

Through his $300,000 National Science Foundation-funded project, \u201cThree-dimensional Geometry Effects on Flow-induced Vibrations,\u201d Sharan will conduct simulations to investigate 3D structural vibrations, identify links between shapes and vibration behaviors and develop methods to modify shapes for vibration control.<\/span><\/p>\n

\u201cThere is growing interest in drones delivering packages in urban areas, where environments are often chaotic due to buildings, cars and other disturbances,\u201d Sharan said. \u201cThese aerial vehicles must withstand severe winds and gusts. So, what geometric modifications can enhance their stability and robustness?\u201d<\/span><\/p>\n

Sharan\u2019s research can improve the design of structures vulnerable to vibration from wind or precipitation and enhance energy harvesting technologies that convert unstable vibrations into electricity.<\/span><\/p>\n

The groundbreaking aspect of Sharan\u2019s work is a new computational method to accurately simulate flow over moving 3D geometries. <\/span><\/p>\n

While 2D structures like circular cylinders have been well studied, 3D geometries remain underexplored due to high computational costs and limited accuracy.<\/span><\/p>\n

\u201cTypically, thousands of processors are needed to run these simulations, often taking days or weeks, making them cost-prohibitive,\u201d Sharan said. \u201cWe\u2019ve developed high-order methods that can handle complex geometries at a much lower computational cost.\u201d<\/span><\/p>\n

Sharan said his team will formulate approaches to modify the shapes to control vibrations by analyzing the geometry facing the flow (forebody) versus those trailing behind (afterbody). He\u2019ll experiment with different shapes to evaluate how such modifications influence flow and vibration dynamics.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
