SUMMARY:The Hanin Lecture - Hypersonic Aeroelasticity and Aerothermoelastic
 ity - a Multiphysics Challenge
DESCRIPTION:Lecturer:Prof. Peretz Friedmann\n Faculty:Department of Aerospa
 ce Engineering\n Institute:University of Michigan\n Location:Classroom 165
 \, ground floor\, Library\, Aerospace Eng.\n Zoom: \n Abstract: \n Details
 : \n A concise review of a series of studies on aeroelasticity and aerothe
 rmoelasticity of hypersonic vehicles conducted during the last 18 years\, 
 by the author and his students will be presented. These studies have focus
 ed on a few basic configurations: a typical section\, a panel\, a low aspe
 ct ratio wing and an idealized model of an entire hypersonic vehicle.  In
  these studies the complexity of the problems considered was progressively
  increased demonstrating the multiphysics nature of hypersonic aerothermoe
 lasticity.  This sustained activity has recently culminated in the develo
 pment of an integrated aerothermoelastic computational framework that gene
 rates a high fidelity model. The framework consists of a Navier-Stokes aer
 odynamic solver based on a modified version of the Stanford University mul
 tiblock (SUmb) code\, a finite element structural solver for moderate defl
 ection of composite doubly-curved shallow shell with thermal stress\, and 
 a finite element thermal solver for heat transfer in composite shallow she
 lls with nonlinear material properties. The solvers are coupled using a pa
 rtitioned scheme. The aeroelastic behaviors of 2D and 3D panels are invest
 igated using the computational frame-work. The 3D effect and Reynolds numb
 er is found to have significant influence on the critical flutter paramete
 r\, and limit cycle amplitude.
