Investigation of Quartz Ablation in the VKI Plasmatron Facility: Comparison Between Experimental and Numerical Results

Boekbijdrage - Boekhoofdstuk Conferentiebijdrage

We study the ablation and transient thermal response of a quartz sample in air plasma. The experiment is carried out in the Plasmatron facility of the von Karman Institute for Fluid Dynamics. The aero-thermodynamic environment reproducing the atmospheric entry in the boundary layer of a test object is selected with cold-wall heat flux around 2.6MW/m2 and test chamber pressure of 100 mbar. These conditions leads to surface temperatures higher than 2500K and overall recession of 2 mm. We propose a numerical comparison based on a traditional transfer coefficient model with thermochemical ablation tables and a sensitivity analysis evaluating material properties and flow conditions influence. The proposed work aims at providing experimental data and improving ablation models to predict the atmospheric entry of space debris silicate materials.
