Abstract:

The problem of interest is the development of a physics based model for conducting high-fidelity simulation of afterburning munitions, which are unique in that that they contain solid and/or liquid fuels that continue burning after the initial detonation to raise the temperature, enhance the overpressure, and strengthen secondary shock waves. From the standpoint of first-principles modeling, accurate depiction of dynamic mechanisms such as shock compression, multi-phase effects, stiff chemical kinetics, reactive heat release, etc., is a complex undertaking that challenges modeling efforts. This is due in large part to the very stiff spatio-temporal conditions inherent in these highly non-linear and very transient processes. Energy deposition can be spatially localized with a wide range of time scales (fluid dynamic, activation and reaction scales) whose numerical resolution requires extremely fine spatial and temporal discretization. A multi-phase CFD approach is proposed to model energy deposition scenarios of interest to the US Navy, with the model also finding utility in identifying the dominant physics, supporting the development of scaling laws and providing interpretation of test data. The modeling will be closely supported by fundamental experiments in a laboratory environment that will supply crucial data for characterization of key sub-models within the overall CFD model.
