Center Innovation Fund: SSC CIF

Development and Validation of Propellant Detonation and Propagation Modeling Methods

Completed Technology Project

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.
