    Abstract

    We aim to develop a model capable of simulating the surface chemistry and material erosion involved when a re-entry vehicle descends through the atmosphere. Our starting point is to simulate the erosion of a fcc crystal slab due to cluster bombardment, using the model Lennard-Jones potential. From this, we plan to scale up towards Direct Monte Carlo Simulation approaches for the gas dynamics above the surface.
