Overview of Ablation Modeling and Simulation at Sandia National Laboratories: Past, Present and Future

Description
This talk will overview ablation modeling and simulation at Sandia National Laboratories, past, present and future. A historical view of ablation simulation capabilities will be presented, followed by a discussion of current work being done to advance our predictive capabilities for ablation problems. Ongoing efforts involve the development of an ablation thermochemistry code, which is being used to solve the thermochemistry problem on-the-fly, hence offering an efficient and more accurate by-pass to traditional interpolation of pre-computed tabular ablation data. This capability has been coupled to Chaleur, a Sandia developed 1D ablation code. Development of a 3D, finite element based ablation code that leverages the ablation thermochemistry code is also underway. This new ablation code involves the investigation of porous flow models and robust mesh motion techniques. Future objectives of this work involve coupling these ablation capabilities with a reacting flow CFD code.
