Development of inverse methods for reconstruction of flight environments on ablators
… due to the harsh heating environment and surface recession. Thermocouples installed several millimeters below the surface are commonly used to measure the heatshield temperature response, but an ill-posed inverse heat conduction problem must be solved to reconstruct the surface heating …

Scale-bridging molecular dynamics simulations of plasma-surface interactions
… manufacturing and biomedical industries. Plasma-surface interactions can be divided into two categories: controlled and erosive. Controlled plasma interactions are used to pattern the surfaces of materials to achieve desirable electronic and mechanical properties in an ionizing chamber. Examples …

A Lagrangian, Discontinuous-Galerkin Material Response Solver for the Analysis of Ablative Thermal Protection Systems
… char and pyrolysis gases blow away from the surface. Their use is common in high-velocity hypersonic missions through dense atmospheres, in contrast to other materials such as reusable TPS, which are often used in lower heat flux scenarios. Analysis of ablative TPS materials is challenging …
