Description

Research Topic Description, including Problem Statement:

When an explosive reacts, either through detonation or deflagration, a complex series of chemical reactions occur rapidly generating an explosive shock wave coupled with intense thermal effects in very short (microsecond) timescales.

The effects of combined thermal and shock exposure to materials in contact with the explosive charge, including reactive chemicals, biological materials or mitigation materials, is not well understood.

We seek research proposals that will increase our understanding of the near field behavior, including thermal and shock. This understanding gained through this research should be of sufficient accuracy to allow its application to assessments of novel devices.

Example Approaches:

  • This project would include both computational and experimental aspects. Computational and theoretical approaches will be developed to predict the near field behavior of different energetic materials, including conventional, commercial and improvised. This could include a combination of thermochemical calculations, ab initio molecular modelling and hydrodynamic simulations and may integrate existing models.
  • The modelling data would be complimented using precision experiments to measure the near field behavior, including the intensity and duration of the thermal output in the near field region.
  • Synergistic effects between the shock/blast wave and the thermal effects would be assessed.
  • An experimental method for reproducing thermal environment of an explosion in laboratory-based experiments could be developed.

Relevance to the Intelligence Community:

Assessments are frequently made on the viability and lethality of different improvised devices. In order to do this, we draw on significant existing knowledge base including data of the far field and fragment driving effects of explosives. However, due to the proliferation of knowledge on the internet, threats combining different methodologies are becoming more common. Due to the additional complication presented in these scenarios, we do not have a complete understanding to provide an assessment of the risk posed by these novel threats. This project will provide a validated understanding of key material interactions and potential synergies allowing validated scientific assessments to be made.
