I. Introduction
Go to contribution page
Ablation experiments have traditionally been conducted using plasma wind tunnels. Plasma wind tunnels can generate high-temperature flows for relatively long durations and are suitable for measuring recession rates and internal temperature histories of ablative materials. However, because the test gas is generated as a plasma flow, its degree of dissociation can be higher... -

Background of the Study
Go to contribution page
Recent studies in non-equilibrium thermochemical CFD suggest that boundary conditions involving the ejection of reactive ablation gases from the wall can increase chemical heating near the wall at moderate mass fluxes, potentially leading to an increase in heat flux [1]. Furthermore, under high-speed conditions such as hyper-orbital reentry and entry into the... -

Workshop topic: Ablative-Radiative TPS and Meteors
Background of the study
During high-speed atmospheric entry the shock-heated gas emits and absorbs strongly, and radiative heating becomes a significant (at the highest speeds dominant) contribution to the heat load on the vehicle's thermal protection system (TPS). At lunar-return velocities (around 11 km/s) the radiative flux is...
