Development and Validation of Propellant Detonation and Propagation Modeling Methods
Project Introduction
The project is to leverage work done by NASA SSC and NASAMSFC as part of a recent NESC investigation into developing validated tools for modeling blast wave propagations in test facilities. While significant accomplishments were made during this investigation, a key recommendation was to determine a valid engineering-level approach for predicting cryo-vapor cloud detonations [VCDs]. Specifically, the robustness and accuracy of reduced finite-rate chemistry mechanisms will be investigated and compared to more computationally intensive elaborate mechanisms. The validity of these mechanisms in predicting the VCD and its subsequent propagation through complex structures will be studied using the Loci/BLAST and Loci/CHEM CFD tools.
More »Anticipated Benefits
This technology will enable safer rocket propulsion testing for NASA funded missions such as the Space Launch Systems (SL) and COTS programs by providing an improved predictive capability for catastrophic events.
This technology will also benefit all future rocket propulsion testing and/or launch systems.
This technology may be used by the commercial space industry for ensuring safe unmanned and manned space flight missions.
This technology may benefit DOD propulsion testing and/or launch systems. It will also benefit other agencies such as Homeland Security.
