High-Speed Fluid-Structure Interaction: Panel Flutter and Surface Morphing Control

This is a virtual event being held via Zoom

Dr. Vilas Shinde, The Ohio State University 

Abstract: High-speed (supersonic/hypersonic) aircraft are inevitably exposed to extreme loads (pressure, thermal, drag, etc.) due to, for instance, transition to turbulence and shock boundary layer interaction (SBLI). Successful design and control are predicated on accurate assessments of the multi-physics interactions between aero-thermo-dynamic loads and flight structures. In this talk, we discuss recent results on fluid-structure interaction (FSI) dynamics between skin panels and SBLI. To address the large number of pertinent parameters, we systematically study the response of flexible panels by gradually increasing the flow complexity as well as the effect of structural parameters on the physics of the interaction. The analysis is greatly facilitated by a newly developed fluid-thermal-structural-interaction (FTSI) solver framework capable of fully coupled/uncoupled analyses. The FTSI solver framework is then successfully extended to control flow separation and structure-sensitive unsteadiness. For this, a time-accurate surface morphing technique is implemented based on local separation criteria to guide surface deformation.

About the Speaker: Vilas Shinde is a postdoctoral researcher at the Mechanical and Aerospace Engineering Dept. of the Ohio State University (OSU). Before joining OSU, he worked as researcher at the French National Center for Scientific Research (CNRS). He earned his PhD in Fluid Mechanics from the Ecole Polytechnique and MS in Turbulence from the Ecole Central de Lille in France. His main research interests lie in theoretical and computational low/high speed fluid-structure interactions. He is also interested in reduced order modeling, turbulence modeling, flow stability and transition.
