| Abstract Scope |
Woven carbon fiber composites show potential for use as an ablative thermal protection system for atmospheric re-entry vehicles traveling at hypersonic speeds, but testing can be a time-consuming process. We created a process to import complex woven geometries into the open-source Macaw application built on the Multiphysics Object-Oriented Simulation Environment (MOOSE) framework. Macaw uses the phase-field method to simulate the ablation process of the fibers and the char matrix on the outer layers of the heat shield material. This model is fully coupled with a heat transport model and has a chemistry model developed from that Air-Carbon Ablation model. This model allows for testing different heat shield woven fiber geometries to see how it can affect the fiber and matrix oxidation rates before doing expensive and time-consuming experimental tests. |
