For extra-orbital missions, ablative materials have always been, and still remain, the primary choice for the design of atmospheric re-entry heat shields. Because of the many uncertainties associated with the usage of such material in complex aerothermal flow environments, it is important to understand and quantify the effects of the phenomena at play. Many specific areas of research can lead to a better understanding of the underlying physics of aerothermodymamic ablation. More specifically, the topics discussed will touch upon spallation, the coupling of material response and CFD codes, the oxidation of ablative material, and flight experiments. An overview of future challenges in the field of aerothermodynamic ablation will also be presented.
Alexandre Martin obtained a B.Sc. in Physics in 1998 from the University of Montréal (Montréal, QC), and a Master’s and Ph.D. from the Department of Mechanical Engineering at École Polytechnique de Montréal (Montréal, QC). He worked primarily on plasma ablation, with an application on industrial high-voltage circuit-breakers. After continuing this work as a Research Associate at École Polytechnique for a year, he then moved to the University of Michigan (Ann Arbor, MI), where he worked on the material response of atmospheric re-entry vehicles. Since January 2010, he has been a faculty member in the Department of Mechanical Engineering at the University of Kentucky (Lexington, KY). His current research areas involve: ablation, aerodynamics, aerospace, aerothermodynamics, compressible flows, computational fluid dynamics, fluid mechanics, gas-surface interactions, heat transfer, hypersonics, material response, numerical methods, plasmas, radiative heat transfer, re-entry.
