US National Lab Models Rocket Propellant Fires


A new US presidential directive has required Sandia National Laboratories researchers to use computer modeling to conduct a predictive, public-risk analysis of accidental fires that might occur during the launch of NASA space missions carrying radioactive materials. They say they analysis will combine experimental test data with multiphysics, high-fidelity models, an approach not previously attempted. The researchers are building an interface that will let them update, add different predictive features to, and validate their overall model. They are now evaluating the Rocstar software code that University of Illinois scientists developed and that may help with the modeling. (PhysOrg)(Sandia National Laboratories)
