Theme 1: High-fidelity micro/meso scale physics
We use a wide array of modeling and imaging tools to resolve the fluid, radiative, and chemical processes occurring between hot gases and micro/meso structure of materials. The structure of materials is resolved using x-ray computed micro-tomography and an in-house digital micro/meso structure generator solver. The fully-resolved structure acts as the input into our thermochemical modeling tools. CTFL has the capability to capture fluid, chemical, and radiative transport through these complex structures. These techniques have been primarily applied to thermal protection systems (TPS) materials that protect space capsules and leading-edge vehicles during hypersonic flight. The example below shows a tomographic scan and fluid transport through a TPS material, FiberForm.
