Abstract: | An adaptive finite element method for high-speed flow-structure interaction is presented. The cell-centered finite element
method is combined with an adaptive meshing technique to solve the Navier-Stokes equations for high-speed compressible flow
behavior. The energy equation and the quasi-static structural equations for aerodynamically heated structures are solved by
applying the Galerkin finite element method. The finite element formulation and computational procedure are described. Interactions
between the high-speed flow, structural heat transfer, and deformation are studied by two applications of Mach 10 flow over
an inclined plate, and Mach 4 flow in a channel.
