Verification of a conjugate heat transfer tool with us3d

The accurate prediction of thermal responses is important for optimizing the design and operability for hypersonic flight vehicles. In order to efficiently simulate this process, a coupled conjugate heat transfer solver was developed. The simulations were performed with US3D, an implicit finite volume unstructured compressible flow solver, with a newly developed implicit finite element transient heat conduction solver. The finite element solver is verified by comparing with analytical solutions for a bar and cylinder with Dirichlet and/or Neumann boundary conditions. Finally, the boundary layer transition (BOLT) vehicle is simulated for a segment of the trajectory. Results show the heating of the leading edge through time and the three-dimensional heating of the vehicle.
